We bought one of each on day one for R&D purposes. I absolutely agree. The Air is absolutely the better machine and it’s cheaper. In our benchmarks we actually saw better performance out of the Air most of the time (bursty workloads) and the only thing we could think of was that the bigger heat sink in the Air provides better cooling than in the Pro most of the time, unless you have really long compiles where the fans kick in.
You can even do a little (reversible) mod to the Air where you add some thermal pads, effectively turning the entire bottom into a giant heatsink. It'll get a little warmer to the touch than before, although not uncomfortably, but the sustained performance gains are definitely worth it.
