PDAs have faded in popularity given the presence of smartphones, which are PDAs with phones built in. Most of the features you desire are standard across most such devices nowadays, so there is no shortage of options.
The key is to find the programs to expand your phone's capabilities rather than looking for the exact configuration out of the box. For instance, Windows Mobile users can install gAlarm to add custom alarms, quiz/maze verification (to ensure you're really awake), etc. Likewise with gProfile, which automatically chages your finger, runs/closes programs, etc. based on time/day, scheduled appointments, and cell tower being used.
The best way to pick a smartphone is to try the demo models at local electronics and phone retailers, seeing which you like best. However, I will note that Android is an operating system while Palm and LG are companies that manufacture smartphone. LG makes a large variety of models while Palm was recently acquired by HP after financial difficulties.
Regarding operating systems, iOS is only used by Apple and, while easy to use with thousands of apps to choose from, it is not very customizable. Android is fully customizable, but is still a little rough around the edges. WebOS is only used by Palm and is in a state of transition. Windows Mobile is being replaced by Windows Phone, due out later this year with much anticipation and little history.
Hope this helps,
I am in need of a good quality PDA. For the absent-minded user like me to get good use from a calendar, it really must be quick and flexible to program.
I have a very nice Samsung Eternity, but I found two problems that have given me reason to stop using the calendar. One is the time-consuming quantity of submenus that are required (some frustratingly hidden), and the other is that the phone rings while I am teaching class.
I need a very good PDA/appointment reminder that:
1. is VERY quick and easy to set appointments with
2. will wake up the calendar alarm without also allowing the phone to ring
3. has flexibility for alarms to be set for several advance times
I am not sure about the PC syncing (Windows XP), since I have never tried it, but it sounds like a useful feature. These other desires are expendable & secondary: to have a phone on board, built-in GPS (to avoid the costly AT&T subscription), wi-fi, bluetooth, long battery life/replaceable battery, good camera, etc.
After web research, I think Palm, LG, and Android might be easy to use, but I am becoming confused over all the smartphone choices.
Thanks for your suggestions,
