Solar Bottle solar-powered water purification

Generally an energy-intensive, wasteful operation, but designers Alberto Medo and Francisco Gomez Paz have done a neat end-run around those problems with their Solar Bottle, a portable water bottle that purifies water using the sun. The bottle, which holds just over a gallon of water, uses a purification process called SODIS that takes six hours to kill off a whole host of baddies, including Oregon Trail favorites cholera, typhoid and dysentery. Just a concept for now, but the design has been well-received and won several awards, so hopefully someone will step up and take it into production soon.

Samsung's Croix: yet another 'iPhone rival'

Honestly, we're getting a bit tired of all these so-called iPhone rival handsets, but Samsung's elusive Croix doesn't do a whole lot to shake the stereotype. The mobile, which happens to boast a very similar layout to Apple's darling (and Samsung's own F700), just won an iF Communication Design Award 2007, and while details are scant about the actual hardware, it sounds like Sammy is hoping to grab your attention with a sensationally sleek interface (seen in detail after the break). The name, which translates to "Cross" in French, supposedly symbolizes the phone's "progressive continuum, as opposed to discrete transmission from one item to another," and touts an "intuitive interface through on-screen touch input mapping which supports five different ways of interaction." Of course, only time will tell if this thing actually goes commercial (or proves real, to be honest), but it certainly has the look.

IOGEAR

We know, "back to school" isn't exactly a phrase that brings a smile to most students, but IOGEAR is hoping to get you a bit more jazzed up than usual about the fall semester with a new duo of products. Following the Digital Scribe, the firm has now unveiled a 4GB Flash Wallet Drive and 3-in-1 Wireless Phaser Presentation Mouse to presumably help you with your studies. The uber-thin wallet drive ($69.95) measures in at just 3-millimeters thick and ought to hold quite a few research papers, while the wireless mouse ($59.95) combines a laser pointer and track ball to aid you in making those presentations go as smoothly as possible. Both products should already be available at your campus store or nearby big box retailer.

Samsung Spruces Up The Q1 Ultra UMPC

When Riyad looked at the Q1 Ultra he mused upon the fact that adding a solid-state drive would make it a much more attractive proposition and suggested that within the next few months we would see a model featuring one. Strangely enough, just two months after we reviewed the original, the SSD fitted Q1U-SSDXP is upon us, along with two other new models.

Elsewhere the specs are still the same, so the Q1U-SSDXP offers an 800MHz Intel processor, 1GB RAM and a 7in 1,024 x 600 screen; battery life and heat output should improve though. No UK pricing is yet available, but the US model is $500 more than the same spec machine without the SSD, so expect a reasonable premium in the UK, bearing in mind a separate drive costs around £300.

Backing up the most desirable model is the Q1U-XP, which is simply the same specbut with a 60GB hard disk instead. The main problem we see is that eXpansys lists this spec as around £800 and for that money you could pick up a Q45 which is more powerful, offers better performance, similar battery life and 100GB more storage space.

At the lowest end of the Q1 spectrum is the Q1U-ELXP, which offers a 40GB hard drive and a 600MHz processor. While this will obviously provide lower performance, it should offer better battery life than the 800MHz models and could therefore actually pose a more attractive proposition to the kind of market that the UMPC form factor aims to target.

Either way, while I do like the look of the Q1 Ultra and the latest refresh certainly doesn't detracts from its desirability I still wouldn't part with my hard-earned cash for one.

OQO Model 02 Ultra Mobile PC

The UMPC concept has been around for some time now, but in my opinion no company has yet produced a better-designed, more desirable device than OQO. When Riyad saw the company's first miniature PC at CES way back in 2005 he badly wanted to lay his hands on one.

It was about as small as you could imagine a PC being, squeezing in an amazing amount of functionality, but it was the design and engineering quality that made the OQO Model 01 so desirable. The company's latest version – the Model 02 – exudes the same technological pheromones.

It is just as small as the Model 01: at 142 x 84 x 25mm it's about the size of a small but thick ring-bound notebook. It still has that solid, military hardware feel to it. The screen still slides up in one smooth, fluid motion to reveal a QWERTY keyboard underneath. And the chassis is constructed of the same stiff magnesium alloy. Compared to the Sony UX1XN, a comparable Windows Vista pocket PC I looked at recently, this is a mile ahead in terms of engineering quality.

But the Model 02 hasn't stood still, and this latest version represents a pretty big facelift. The most obvious change is the colour scheme, which has gone from gunmetal grey and silver to a combination of matt and gloss black finishes, with the odd flash of brushed aluminium here and there. I liked the old colour scheme because it was different and still managed to look really smart. But though the Model 02 now merges into the crowd a bit more – everyone is doing gloss black these days – it still manages to pull the look off with great panache.

The lines of the diminutive Model 02 have been softened a little this time around, with curved sides where you grip the device. The Model 01 and 01+ were quite blocky and could be uncomfortable for long periods of time, but the Model 02 is much easier on the palms.

Flick up the screen with your thumbs and you'll see that OQO has gone to town on the keyboard as well. With the Model 01 and 01+ we had a usable but occasionally fiddly keyboard. The unusual circular keys were quite difficult to hit accurately and, though better than most smartphone keyboards, this made text entry relatively slow. However, the development guys at OQO have clearly been paying attention in keyboard classes, because the one on the Model 02 is a vast improvement.

The keys are now square-ish, so it's much easier to hit the keys in the first place, and they have more feedback to them too, so it's much easier to tell when you've actually hit a key successfully. More importantly, you can actually thumb-type quite quickly on it. It's never going to match a notebook keyboard for speed, but for writing short documents and emails it's perfect. Again, compared to the Sony UX1XN this is streets ahead, and much more convenient to enter text and web addresses than a plain tablet-based UMPC like the Ubiquio 701.

O2 Cocoon

The quad-band 3G Cocoon is not the first own-branded whiter than white handset I've seen from O2. That accolade went to the ICE. The Cocoon though, is a uniquely oddball mobile in several respects. It certainly looks different enough to be an eye catcher and apparently if you take your Cocoon to the O2 (formerly known as the Millennium Dome) in London, the phone knows what you are doing and will provide you with ‘exclusive content'.

It has a penchant for playing music and while it lacks an outer display it has the mobile phone equivalent of a rolling neon sign on its outer casing. This is actually an LED that scrolls information in large blue lettering across the white front fascia at various times. Oh, and the Cocoon comes with a little stand in which you can pop it to take advantage of some of its features. O2 rather grandly calls this, the Nest.

Let's start with the general look and feel, though. This is a rather large mobile phone for the pocket, measuring 94mm tall, 49mm wide and a rather excessive 21mm thick. It weighs 114g. When the clam is opened it extends to a little under 170mm. The clam doesn't open fully to 180 degrees, stopping short to give the impression of being a little curved and a better fit for your face.

With the clam opened you are faced with a vast number pad and a large rectangular area containing a reasonably big navigation button and Call, End and two softmenu keys. The key arrangement is minimalist and easy to use, which is fine by me.
The screen measures 2.3 inches corner to corner and delivers 320 x 240 pixels and 262,000 colours and crucially, is bright and sharp.

O2's menu system is reasonably clear to follow. Up to eight shortcuts run along the bottom of the main screen and can be customised to show what you prefer, even pointing to individual browser bookmarks. The Cocoon can automatically change its wallpaper daily or hourly.

The Cocoon's curved white outer casing with its rounded top and bottom edges and black sides makes it look unlike any mobile I've ever seen. The casing is made of a plastic that has a semi rubbery feel that's quite nice in the hand, actually.
