Yes. I've manage to baby an early Palm IIIxe for 6 years, & newer HP rx3115 for two years, for "other" daily projects w/o any breakage. But it wouldn't take much to damage them. (Mostly the display from what I've seen of other's damaged units.)
I guess buisness folks are not that active with a suit, tie, and wingtips on. Oh ok. Let's be fair. Pantsuits and flats on. (I wanted to say skirts & high heals but someone's looking over my shoulder & my ribs are still sore from the last time...)
There are "armor" cases out there that can help protect PDA's, but at a cost of a thicker unit, & a thinner wallet. I've got both a Body Glove soft case for the Palm and a Rhino Skin hard case for the HP w/o any failure. I like the soft case better myself.
As for battery life, 5-9 hours of run time between charges is fine with me. Most of the time I'm driving between groups of caches anyway & I'll use the dash GPS in the truck for that travel time. The pocketPC PDA stays off time I get to the site and on the ground. Heck I could be recharging as I drive.
But I do like the idea of a single unit that does it all. Internet Wi-Fi, GPS/Mapping, Data Logging, MP3 Player, Excel. Word, Calendar, Contact lists. If it only had a beer tap too.
