The MacBook Airs actually run PS faster than the MacBook Pros, due to the solid state drive in the MB Air. When I start PS CS5 on my (previous generation) MB Air, It is open and running almost instantly. The same for Photomatix. In the online Apple store, look way down in the lower left of the page for refurbished MacBooks.
Let's face it: despite the product improvements, it's hard to get excited about upgrading to this from the 5DMII, particularly in the face of the Nikon D800 with its 36MP, actually better low-light performance (per DxOMark), lower cost, and the widely-better-regarded Nikon lenses. While I don't know what I'd actually do with that many megapixels, I feel more like switching to Nikon than upgrading to the 5DMIII.
Liysa88: Hi, You all talked about how good the camera is but does anyone knows the weight of the body of EOS-1DX and the EF 24-70 mm F2.8L II USM lens?
It seems no retail stores staff can tell me the answer. Anyone know? Thanks
Canon's website says the EF 24-70 mm F2.8L II USM lens weighs 805g, compared with about 950g for the original version. So the new lens is 150g lighter.
