Nope, I'm not wrong and you just proved me more right with more extreme examples where you push the boundaries. No one is asking to run an Air as a replacement for a Pro workstation where you deal with large data sets and complex filters and no one expects the Air to be equivalent to those.
But the Air is quite capable of running of Photoshop CS5 to do what casual Photoshop users do. You know, the tasks that you could remove CS in front of the 5 and Photoshop could still do (yes, Photoshop 5.0, the thing in the 90s that ran on 32 MB of RAM and a Pentium 100 mhz computer.)
A lot of users over-estimate their computing needs. I get that you are all Pro-level artists that work Photoshop day and night and don't have an image file smaller than 2 TBs, but really, why are you applying your niche needs in pro-level editing to someone asking about casual use ?
Agree x 1000.
Next thing you know, people will be asking for an 11" MBA with 17" display.
There's an appropriate tool for every job. People should choose the appropriate tool and stop complaining that their square peg doesn't fit into the circular hole.
If you're a heavy-duty user with processor-intensive needs, then choose a laptop with a faster CPU. A 13" MBP isn't THAT much heavier than a 13" MBA, and even if you actually believe that it is too heavy, you'd probably would still be willing to carry it around because you have 'real' work to do, and you need a way to get it done; no excuses. This is the way it was in the Stone Age (pre-2008), when
People don't carry around a 15" or 17" MBP because they enjoy the extra physical exercise. They get it because they need the machine that will meet their needs. An MBA will fulfill your computing needs, as long as those needs don't involve movie editing and multiple edit layers in Photoshop.
I'm going to buy the upgraded 11" MBA when it's released, and I intend to write documents, work on spreadsheets, read PDFs, and post at MacRumours and FaceBook while I'm away from home. It could handle my current photographic needs, but I'll still use my 15" MBP to do that type of work, since it's the better, faster tool for the job.
