I own a Palm3e and love it, but here are some things that really bug me about it.

1) No on-line browser
2) Can't send email to a group
3) No built-in connection to Groupwise
4) No (standar)serial, parallel, PCMCIA, keyboard, RJ45 or monitor ports
5) No built in biz apps (Office for the Palm)
6) Dedicated graffiti area is a waste of space
7) Backlight is almost unusable with a hack
8) Menu must be activated from the bottom of the screen
