I would have to agree with erol (I knew I would sooner or later
) ... beware of Pocket PC / Win CE devices. They are not the package they appear to be at first. Think about what you actually
need a handheld to do and how often you want to do it before you buy anything. When you've done that, you'll find that an OS designed for handheld devices - i.e. Palm OS - is much better suited than an OS that was designed for a desktop and then scaled down (i.e. Windows).
Also bear in mind that in the realm of handhelds, M$ are not the market leader, so if you want the best and widest selection of apps (especially freeware), it's on Palm OS, not Pocket PC.
As for hardware, as erol says beware of battery life and be sure you need WiFi badly enough to put up with the power drain. AFAIK Bluetooth is less power hungry ... most Palm, Handspring and Sony devices (all Palm OS) either have Bluetooth built in or can take a Bluetooth expansion card, so this option plus a compatible mobile phone may be better for you.
Pocket PC devices appear to me to be somewhat bulkier than comparable Palm OS handhelds (especially compared to the delicious Palm Tungsten-T3) And finally, don't be fooled into thinking you're getting more hardware for your cash with a Pocket PC ... they apparently have more RAM, but what they don't tell you is that they
need twice as much RAM as a comparable Palm OS device because the Windows OS is so bloated.
Best buy is prolly the
Palm Tungsten T and the best price I could find via Kelkoo was
£249.99 with £6.99 delivery.
