received my 770 today. Writing this posf from this amazing device right now.
So my first impressions.
I opened the box, plugged in the battery and memory card. Then went thru the wizard. Wasn't interested at internet access with phone, so aborted this and did setup the language and the other stuff. After that i looked at the wlan settings and it found 5 wireless lans here. One was mine from over my linksys router. So selected this Wlan, entered the 128bit key and pressed connect. Now the device rebooted. I assume it crashed. So went to the settings again, the key was stored. So set this network as default and connected. No problems at all. Could not work better. It shows always low signal, but works perfect in the whole house. Even better than my dlink card in the pc. So i think the display with signal strength is buggy here.
Then i started the webbrowser and browsed to my own and some other favorite pages. AMAZING, have not seen ant better browser yet on a ppc or other embedded decives. Have seen "opera" in the path of the helpfiles. So must be a opera browser. All pages render like on a deskto p pc. PERFECT WORK. The zoom anf full screen mode is fantastic.
So went to email and did setup an acoount with pop3. Works great too and is very easy to use.
All i can say for mow is: l'm impressed from this amazing device. And i know what im talking about. Had many other devices before. Im looking forward so see many cool apps for this device, and try to write own apps or port some applications from linux.
