My N800 has plenty of memory and power. I use a BT keyboard with it when I want too and have done a lot of easy field work with the open source spreadsheets. Etc.
I am a little annoyed that I cant find the way to update the flash and Micro B browser.
I reflashed my unit twice to make sure I have the lastest of everything and it's still very slow to use internet and don't get me started about the poor Google apps integration.

All that aside, I still love it.. but I really need the answer to fixing the slow internet. I'm even back to using my Palm TX because, since it didn't have flash, - the web sites aren't choking it with flash technology widgets. Makes a big difference if you dont like to watch ads like me.
