It really depends on the usage on it. How much resource demanding things are you doing when mobile? I mainly do spreadsheet, light financial modeling, browsing, outlook, and running Win 7 and OSX together on my air. For the most part the SSD really bolsters the performance and keeps things in check. I don't know if I'd like to be doing a lot of media related processing on it though.
I've noticed when running HD res netflix or youtube videos that other programs may stutter a bit. For the most part though, it has been an awesome asset in the computer bag. Light, tremendous battery life, and quick for everyday tasks (which should suit the majority of the population). Keep out HD video related content, and I can easily open up all of the apps on my dock without much complaint.
Of course, this is all bearing in mind that I have a 2 year old AIR. All your results with the current crop would be much better I'd dare say. The new Haswell MBA 13" is pretty sweet, but I would never consider the 11" device in any situation.
It is indeed the Logitech solar keyboard. It's fantastic in my book because unless you are a vampire, the thing will never lose juice. Never worry about battery level or swapping out. It comes with a cool app that can be toggled by a hot key on the keyboard that tells you much juice you have left and how much light it is sucking in for power reserve. Almost all the time it says 100% power though. I especially appreciate the full sized num pad on the right.
It doesn't run on bluetooth, but has super small nano USB reciever. I personally prefer this as I find that I don't like to tie in necessary peripherals with bluetooth.
I love Apple products, but I tend to only go for the core items: Laptops, and maybe the magic mouse at most (even ditched the iPhone after becoming disappointed with the lack of innovation).
After that, I do not think some of their extra items are worth the money and I enjoy the third party stuff that's out there (Like the HP 27"....full IPS, looks like the iMac display, but at a fraction of the cost!)
