to run lots of software it helps to have lots of power which PDA style phones do best...heh
well, i'm not that up on what the latest models do (despite my being the mod here

) however i can say that i enjoy my MDA Compact that i've had for the last year and a bit, so if you want a more phoney (err..that doesnt sound right does it?) version, then consider the T-Mobile SDAII......dunno quite how good it is compared to other makes, but the MDA Compact series of PDA style phones are pretty good in general......
however the only other make i ever owned was Siemens (pre-BenQ).....i didnt like most other brands around at the time (mainly the one beginning with N...heh) as i found them too plasticky and prone to failure going by the amount of times my friends would be sitting there finding problems with them...lol..my Siemens never broke down on me, hell, the first one, the S6 still works if i juice it up (altho the battery only holds for about 20 minutes now...and i dont mean talktime....hahaha)...not bad for a, um, oh crikey, 8 year old phone? i think, longer? cant remember now..lol
last Siemens was a SL45....ahhh...the piece de resistance or however the phrase goes.....simply the most beautiful phone ever created for looks, and the ONLY phone i ever bought for looks...lol..normally i only buy for function....but that phone just said.....MEEEEEEEE....so i waited till the price came down and bought it (£300 for a phone on contract brand new? are you mad! my MDA Compact which at the time had only been out for a few months at the time on t-mobile iirc only cost me £10 with a 18 month extension to my £14 a month price plan that i never spend more than £2 extra on...lol)......ok, think i'll end this here, its gone 4am and i'm rambling thanx to Nottage Hill and their finest Chardonnay...lol
