I haven't touched my N800 since I bought my N810, a year and 3 months ago. I haven't touched my N810 since I bought my G1, in September. And, I'm a hard core unix geek. Have been for 22 years. I refused to even take a mac seriously until it had a unix core (and, because I was a NeXT geek back in the day, mac is what I primarily use now). So, the idea that the N810 has a fully accessible *nix layer, and Android does not, seemed like it might bug me at first. But it hasn't. Not even a little.
