I'm looking at the possibility of a PDA for carrying around with me for recording service work, travelling details, running some specialist thermodynamics software and for storage of some technical manuals as pdf's to save carrying bulky handbooks around. I've had a dig around and some PDA's seem now to have 4" screens that would be a plus when viewing files. I'm not bothered about phone, GPS and the rest. I am not that keen on the Palm TX as Palm seem to have given up on them, the support seems to be poor and reliability seems to be iffy even though the OS is supposedly more efficient. There seem to be issues with the OS software freezing and stuff needing resets although the latest Windows software seems to be better from what I understand. Robustness is important rather than looks as it is an engineering environment. TIA Steve
