I've been looking for a replacement for my 810 since I bought it in 2007.
I really wanted the same size, unix, better camera, and a source for stylii .

I "cut my teeth" on an HP95LX about 1995, then went thru a 100LX and 200LX. Then sat it out until the 810 came along. I tried a slew of PDA's, none fit the bill.

The bill:
Screen of decent size
Easy input
OS I can work with (I'll have to learn some Android )
Good connectivity
Community support (I learned early on never rely on mfg support)
Storage

Everything that's come along since has been useless to me. The Dell looks like it will fit in my shirt pocket. And to me one of the most important thing is to have your tools with you. It will be at about the max range of shirt pocket, but I won't need cargo pants.

Since 1995 I've been one of the geeks that when something came up in a meeting I could usually just whip out my computer and get an answer or fix things. I've remoted into Unix computers in Bosnia to fix things, with my 95LX. Ever since I got the N810 my peers were amazed. They would have to "go to their computer" or "get the laptop", I'd just wi-fi in and have the answer.

The iPhone looked great, but too small. The Newton and iPad too big.

I hope to be able to order my Streak soon.
