Hi, Is anyone out there already doing Rails on a MBA? I am about to buy one but I would love to hear some word about performance. Textmate is not too heavy duty but I like it to be snappy at least like my 2.0 C2D MB. I know David has one, but it is the SSD and he says its like 30% slower than his 2.4 MBP. I am thinking of going with the 1.8 HD, any word about performance compared to other computers? (not benchmark, I am a sympathetic person please tell me your feelings).
