NCIX.com - ASUS Eee PC 8G (Pearl White)
How can I say this clearly enough? This is what I consider to be the ultimate PDA. Okay, it's closer to a UMPC without the touch-screen, but the unit is simply wonderful for concept and I absolutely need one of these.
Admittedly the 8G may be a little excessive based on my projected budget for such a device, the 4G being a little more affordable and available in black (preferred) may be cause to pass on the higher model, but the allure to such a device is the size and flexibility.
While there have been sightings of Windows XP and now Vista on this little monster, the native Linux OS is just fine with me. The ASUS site is fairly non-technical in it's presentation of this little wonder, but I know this is on my 2008 buy list. (I'd show you, but their site was unreachable at the time I wrote this)
UPDATE: I've seen one of the 2G Surf models up-close. Perfection. I recommend for anyone why must stay connected to people while mobile or simply to have an enhanced PDA. I may even scale down my intended model to a 4G and upgrade the RAM (you cant upgrade the RAM on the Surf models, but they are capable). I'm waiting until May for my own. Priorities.
