most of those apps you mentioned are available on the S60... you just have to search more... including terminal services, and torrent, MS Office compatible app had always been there for the S60, as far as i can remember... S60 even have an internet server now...
as for games, there are also a lot, even emmulators for old game consoles...
still, basically S60 is priced half of the cost of the WM PDA and basically cost as much as the WM smartphones....
the only thing S60 dont have much is that we do not have to spent soo many hours (err, days) tweaking it to make our BT voice dial works, tweaking it so dont it doesnt have to have a mind of its own, i mean random reboots... what else, oh i know that some of the WM smartphones dont have a dedicated reset button now, so they have improved, but with S60 we never had, it... in fact i have not rebooted my E61 for at least 5 months now, and it is my work phone, and yes i can make calls, every time, i dont have to coax it...
there was a time when the PDA2K was the greatest among the WM PDA and i almost bought it the 1st week it came out... it was like buying the Mercedes-Benz S600 of the PDA world... imagine my disgust when, almost all the WM PDA forums i went through was saying you have to goto the registry and do this and do that, so that it will run smoothly!!! can you imagine, buying a an M-B and as soon as you got it, you have not even driven 5miles and they will ask you to take it to the shop coz we need to tweak it so that you can drive it smoothly and fast!!!
after that i never looked again at WM, perhaps i should look at it again to be fair, but apart from the TyTN and the K-JAM, there is nothing i can consider very interesting...
i would like to give WM5 a try, but with the E90 coming, it will be very hard to divert my gadget savings to a WM device, perhaps not untill they have removed the dedicated reset button, have great cam, a full working BT, and i can use it out of the box...
hacking is great dont get me wrong, customizability is even better, but it should not get in the way of out right useability... S60 is very much customizable, and hackable as well, WM PDA are more hackable, yes! but too much hacking eats away too much time, geeks do have a social life too....
