No, please don't.

Seriously, batpenguin is right -- it's NOT a phone. It does well to play back music, videos (needs optimization), and internet media streams. It does a much better job of web browsing than my Windows Mobile devices, my Nokia E51 and a Nokia E90 that I've been playing with for the last week and a bit. It's not the fastest device out there, but it beats having to carry my notebook around (especially in cramped spaces like aircraft) for entertainment and online activities.

I use Skype and SIP (via VoIPBuster) everyday for calling my wife and she can't tell when I'm calling from my PC and when I'm calling from the N800.

Handwriting recognition isn't as good as I had it in the Newton MessagePad 2100, but it works as promised. I'm not a big fan of the virtual keyboard, but that works as well. Flash works as well, so that's a big plus for me since I use WeBot on both Windows machines at home, so I have my full collection of music and pictures available to me any time.

My N800 is usually hooked up to my office WLAN or my home WLAN, and to my E51 smartphone's 3G data connection via BT.

It doesn't do office applications well, and that's doesn't bother me one bit. My N800 is an entertainment and web device, not for work.
