Macbook Pro (2010) vs Macbook Air (2011)

I would look at the specs for each and then decide. I have a Macbook Pro mid-2010 and like all the ports (on the sides) it includes along with the DVD/CD drive. The Air doesn't have a DVD/CD drive nor the same ports on the sides as the Pro. The Pro expands to 8GB of RAM. The Air only 4GB. I also like the 15" screen on the Pro compared to the 13" of the Air. The Air's SSD drive is faster (from what I've heard) than the Pro's 5400 or 7200 drive. However, the Pro has more space on the hard drive.

It really boils down to what you want in your laptop. You have to decide.

The 1.8GHz dual-core i7 Air is 32% slower than your 2.66GHz dual-core i7 Pro in all respects other than hard drive speed. In highly disk-intensive operations, the Air's SSD may make up the difference, but in pure processing operations, your Pro has a big edge. For graphics, the Air's integrated GPU with shared VRAM is considerably less powerful than your Pro's discrete GPU and dedicated VRAM. Nothing in the Air is upgradeable; your Pro can be outfitted with a larger hard drive or a faster SSD and twice as much RAM as the Air will ever have. All the non-resizable user-interface elements (menu bar and its text, dialog boxes and their text, tool palettes and toolbars in many apps, etc.) will be dramatically smaller and may be hard to read on the Air, unless your Pro has the optional high-resolution 1680 x 1050 display, in which case things will be the same size on the Air screen, but you'll see less of them because there are fewer pixels in its screen.

I think sticking with the Pro is a no-brainer. To lighten your load, leave the mouse at home and use the wonderful features of the MBP's trackpad. The Pro will never be as light as an Air, but it's a substantially more capable computer, and best of all, you've already paid for it.
