Looks fine for its purpose, but Linx, a 2GB memory and the crap battery life are questionable?
You could of course throw on Windows 2000 (653MB iirc) but anything like XP will be an impossibility, even with the 4GB model.
As you say, it does what it says on the tin, but you can also get PDA's and phone-PDA's that do all that nowadays, in a friendlier enviroment then Linux and with as much power.
Check out the o2 XDA Exec, they can be had for less than £200 brand new on eBay from reputable sellers!
At this level and for them needs id prefer to go for a PDA rather then a laptop wannabe.
