That guy does not compare a 17" laptop to a 11" but the 13" MBA to 13" MBP, and I completely agree with them.
Finally, someone that actually READ the post.
The fact that I own the 11 MBA and 17 MBP is not the comparative point. The comparative point is Air vs. Pro - regardless of the size of the machine, because of course, from a processor/RAM perspective, the 13/15/17MBPs are not that distant from each other in this revision. However, no fair comparison can be made between ANY MacBook Air and ANY MacBook Pro for true productivity. That's my point.
If you want a super light laptop that can "get the job done" and aren't much caring about the price, then by all means the MBA will do fine. My point is to refute some of the false claims that someone made that are supposedly "advantages" of the Air over the Pro that aren't.
Beautiful display -
if anything the MacBook Pro wins here. Press down on a MBP's screen, then press on a MBA screen. The quality of the MBP's screen is superior. Otherwise it's the same frickin panel.
Improved gaming performance.
Seriously? You do realize that the GPU and CPU are the two main components for gaming - both of which are spanked by the MBP, right? MBA might have nVidia, but its chip is not all that.
Louder speakers. Than the 13?
I find that laughable. The MBA has more treble. That's not "louder". Clearer, maybe. All of the Pros have louder audio than the Airs.
Thin and light.
This, and the one below, are the ONLY two things the Air has as advantages. Period.
Overall amazing aesthetics.
Keyboard is very easy to type on.
Same frickin keyboard as the Pro.
Fast boot and application load times.
Throw a SSD into a Pro and it will smoke the Air.
When I talk about true productivity I'm talking about:
- Recording a 1080p RAW HD video.
- Importing into Premiere Pro for advanced editing and effects.
- Rendering the video at 1080p 29.97fps.
- Chopping and editing.
- Encoding and exporting into 1080p H.264 Quicktime using the Premiere built-in encoder or Handbrake (likely Premiere's encoder).
All while running a demo in one VM and music file management in another, with email open, Firefox, Chrome, Entourage, and Remote Desktop managing three other computers, with 10 network shares copying files. Guess what? That Air will start smoking, figuratively speaking. The Pro, like the iMac, will laugh it off and get it done. Might seem an odd use case, but it's not when you work in an industry where you need to get that type of stuff done constantly. It's a day in the life and the machine needs to handle it as such. The Air is not that machine. The Air is the machine I take when I want to just take quick notes, or do quick lookups, or remote to a customer's site really quick. Something small and painless where I know it won't choke.
