Buut no built-in ethernet port and $29 extra for a USB dongle for ethernet. So, the laptop fits in an envelope, but if I want to use it in a wired environment, I've got to have a dongle hanging off of it. Lame.
Integrated battery is sort of lame too. I realize laptop batteries have gotten a lot better (I went through 3 on my original Inspiron 2100, and I'm still on my first with my Dell 700m, but still.
