Bought one a couple of weeks ago, and it really is superb! The best gadget i've ever bought. really hooked on it now. I paid 108 quid off ebay for it,
Cheapest here is 137 pounds.
You must also buy a decent metallic case for it to keep it safe from bumps and bruises...
But I can honestly say it's amazing and I'm delighted with it. Simple as that...
Loads of freeware software out there to personalise your pda, it took me 5 minutes to set up, charge (well 8 hours to charge) and sync with outlook straight off. A couple of my chums have one and we're all as chuffed with it as each other.
If I can help you in any other way, please feel free to ask.
