It is an Ultraportable. It is not suppose to be a speed demon. I have one in my lap right now and its doing amazing writing this thread
I have an MBP for mild lifting and a PC for gaming.
A 3lb ultraportable as sexy as this one has to come with compromises.
I think the battery life is slightly better and the slight speed bump in cpu which you may not notice in most actions you take and a HUGELY lower price. I think thats the real upgrade, the price. I paid 1738 with overnight shipping for a MBA with 128GB SSD and 2.13 core duo. I think thats a big ass upgrade
If you are looking for power, I would recommend an MBP.
