I love my MacBook Air. To everyone who asks, I rave that it's my favorite of all the computers I've owned. Sleek, light, ultraportrable, yet a workhorse with a full-sized keyboard and screen and plenty of memory for my cloud-computing tendencies.
The original knock on the Air, back when it was introduced, was the lack of a disc media drive. I bought an external drive with the machine, but I can count on one hand the number of times I've used it in three years. It makes no sense to carry a heavy drive every day when you might need it once a month to install software -- and with downloadable software the new norm, that's a level of use that few people will ever reach.
My original Air is a little more than three years old now. It's served me well. But it's showing signs of age -- increasing slowness, the spinning beach ball, a lot of force-quitting needed. I'm inclined to think it could be rehabilitated, slimmed down, retrofitted for a different purpose, and live another several years. My few tentative steps in that direction have made some difference, but I still have trouble playing video and keeping high-demand applications (like Twitter clients) open.
And Apple has introduced the next generation Air, which features a solid-state hard drive standard. It was an option on the first generation, but I didn't get it. I prefer iPad-style flash memory storage -- no moving parts to wear out.
It may not be the right time to replace my Air in terms of getting a closeout deal of some kind. And I don't have any urgent need for a new machine for any particular projects or functions upcoming. (Well, except for my movie-clip-laden orientation talk to the new freshmen in early June.) But every time I have to shut down and restart to get my applications to run smoothly, or sit through long delays between mouse clicks registering, I start dreaming about a new dream machine -- and feel a little guilty about the love I'm leaving behind.
