Windows Mobile or Ultra Portable PC ?
I have an OQO to play around with for a while, this is a fully functional PC in a palm sized (depending on the size of your hand) form factor. The device runs on a Transmeta processor which seems to scale from 300MHz to 1GHz depending on processor load – the OQO came with Windows XP Professional installed, has a 20GB hard drive, and 256MB Ram – the device has built in WiFi (when I used the device at home it detected my 802.11g and 802.11b networks), and built in Bluetooth support, has USB and 1394 ports, and audio out (no native audio on the device, so you can’t listen to music without headphones – my Shure e3c headphones work really well with the OQO, and my other wma/mp3 players).
So, a quick review of the OQO. I took some photos of the device against an iPaq 3850 so you get an idea of the size of the device.
Side by side comparison of Pocket PC and the OQO

Here’s the OQO and Pocket PC next to each other so you can see the depth of the devices, so far the devices are very similar in size, right ?

The OQO has a screen that runs at 800x480px default resolution, which seems to be good enough for web browsing, reading RSS feeds, using Windows Media Player, Outlook etc… I’m certainly not planning on installing Visual Studio .NET 2003, I’m not sure the screen is large enough for coding!

The screen on the OQO slides up to reveal a thumbpad keyboard, and has a ‘nipple’ style mouse navigation control on the right side of the keyboard (left and right mouse buttons are on the left side of the keyboard) – this combination works pretty well for thumb input – it’s not good enough for your typical speed typist though…

One of the things I really like about the OQO is the innovative extension cable that comes with the device, this plugs into a connector on the base of the OQO and provides Video Out (nice for Powerpoint!), 1394, USB, Ethernet, Audio, and power in – really, really (really) neat.

Add a bluetooth keyboard (I have a Think Outside Bluetooth Keyboard) and you have a really usable device.
What’s really neat is the device is a PC, so it should run all desktop applicaitons… Battery life seems to be around 2 hours which is nowhere close to the typical battery life on my Pocket PC or Smartphone devices, boot times are typical PC boot times (unless coming back from Standby or Hibernate), the device is certainly nowhere close to "instant on" like the Pocket PC and Smartphone, one of the major downsides is the device doesn’t get any data if it’s not on a WiFi network (unlike my Pocket PC Phone Edition and Smartphone devices which get updated e-mail over GPRS, and give me the ability to browse the web and run local applications that consume data from XML Web Services over the GPRS connection), and the device runs pretty darn hot (good for keeping your hands warm on a cold and frosty morning)…
If you have any comments or thoughts on why you would choose Windows Mobile or ultra portable PC, then let me know…
