All these pros, except weight, is really just down to the SSD - which you can get in any MBP trivially. 1. With an SSD, any current MBP would feel just as snappy. 2. Can't get around that - though I seldom feel my 4lb MBP is too heavy. 3. I've always had this, I call it Sleep. 4. My 13" i5 gets me >7Hrs. 5. Eclipse/XCode - will run just as fast with an SSD. Compile times - no contest, i5 beats the crap out of a 1.3-1.86Ghz C2D. The i5 in the current 13" MBP is nearly twice as fast as the C2D in the model it replaced - e.g. even faster when compared with the lower clocked MBA processor. Most things in day to day operation are HDD limited. Anything CPU limited will fly on a MBP compared to an MBA - I'm thinking compiling mostly for developers... I suppose web dev doesn't require compiling much - except when using GWT (which i what I use most often...)
