XDA Exec?

[ffutures]

I was talking to some teachers at work about my problems with the mininote and desire for a pocketable computer, and someone offered me his old XDA Exec - it's the O2 configuration, e.g. unlocked, and I suppose that it's OK as a PDA with Wifi etc., but I doubt I can get up any speed typing on it. Nevertheless it'd be a big improvement over my current PDA, and I suppose I could put the Sim card from my current phone (orange) into it and use it for that too.

Any horrible problems with them I should know about? And realistically how much is it worth? price is something I haven't discussed yet.

Later: Never mind - there's something wrong with it, it keeps locking up for some reason. I shall have to look at other options.
