Dreamy First Night with MacBook Air

Admission: this is my first laptop ever.

In early comparisons this 2.13Ghz, 4Gbyte ram paper weight is an adequate replacement for my monster dual core 3Ghz, 4Gbyte ram Dell desktop running Ubuntu (appropriately named Juggernaut).

I don't do heavy animations with Adobe. My standard fair is light gaming and web scripting front/back end. I'd like to push 3D JavaScript graphics with HTML5 but don't yet have a need.
