I would buy a UMPC if they were a tad cheaper
400Mhz for £200 - not exactly the best performance to price ratio (especially since its an ARM CPU no X86) but still, for its size, it packs a pretty big punch.
PDA's that i've had in the past had dreadful battery life, music players were horrid, and Microsoft don't help with their woeful OS (CE, Mobile etc.)
As for buying a Laptop, sold my Macbook (& xbox360) to get money for my camera in August, and my IBM T43 serves me well enough for most things, but I don't plan on taking it with me on the bus to listen to music on.
It's an iPod Touch ... thats what the fuss is about. Now I'm actually not an Apple fan, I prefer using XP over OS, I prefer using any player but iTunes on my computer - but if they do one thing good, it is the style and user interface of those iPods!!!
My iPod changes menus fast, its touch screen is responsive, and one of the hotter points of debate - the touch screen QWERTY keyboard - is, at least for me, very easy to operate and I can type faster with it than I can any type of buttoned QWERTY on phones I've used (blackberry my mate has) and a LOT faster than the standard phone keyboards.
The music that is kicks out, through standard Apple headphones, is to me anyway, clear and I am able to pick out all the instruments, the highs and lows and the midtones are exceptionally clear compared to the Video iPod and the 2G iPod Nano)
Now most of my music is 128kbps or 192kbps MP3 format, so its not perfect but still they sound good.
