I had both of those. I think I got the most use out of the 701. I took that thing everywhere and used it as my primary laptop. You can probably find pictures

I had both of those. I think I got the most use out of the 701. I took that thing everywhere and used it as my primary laptop. You can probably find pictures of me using it to give conference talks, sitting around at hackathons coding (with a HHKB attached), etc. I used Debian, and even had working WiFi. The 901 I bought later since it seemed like more specs would be better, it was big and cheap feeling. I do remember getting a WiMax stick for it and reading RSS feeds in Google Reader on my commute. That was so novel at the time!
