Tea with AK71: A PDA phone?

Nuffnang is running a HTC mobile phone campaign on my blog for a few days and this triggers something personal in my mind.

Many friends own PDA phones but I have not found the need for one myself so far.  Of course, I have been described by many as an IT dinosaur.  So, I am not a good reference, I guess.

A friend just bought a HTC mobile phone a month ago and he says that it's pretty decent and very useful. Maybe, just maybe, I should consider a PDA phone too.  Do you own a PDA mobile phone? What is your experience with it? Is a HTC good or do you think that other PDA phones are better? I would appreciate any good advice.  :-)
