Macbook Air: 3 Reasons Why Its No Longer a Toy

Today's release of the new Macbook Air lineup vaults the machines from "nice to have, but not enough machine to do any real computing" to "the future of laptops".  I'm speaking more specifically about the new top of the line 13" model.  With the processor upgrade to the Core i5 and i7 "Sandy Bridge" line and the addition of the Thunderbolt port, the two biggest knocks on the Air have been quashed.  Additionally, the keyboard is now backlit which, for me, was a total show stopper with the previous model.

It will be fun to see the reviews from the "experts" (guys with enough readers or money to get the new models early) who slammed the previous model for being too slow, too underpowered and with too few expansion options. As I examine the specs for this new mini-mighty 13" model, I can only find one reason not to buy it: there's too few Thunderbolt accessories to date.  As with any new peripheral interface, it will take the third party guys a while to catch up, but in the next couple of months we will have forgotten about today's shortcomings.  So, why do I think the new Air defines the future of laptops?

1. Moving parts and portability don't mix well. With no hard disk or DVD drive the Air is a true "solid state" machine.  The two most fragile components of a laptop are also the slowest. The SSD is so much faster than a spinning disk that even the previous generation Air with its much slower processor felt snappy and responsive and 256 gigs ain't shabby.  DVD drives are going the way of the floppy disk. I can't remember the last time I slid a disk into my MacBook Pro. Yep, more rugged, affordable and much faster...I'll take it.
2. Core i5 & i7 = Plenty of muscle.  Let's face it, a 1.4 GHz Core 2 Duo is a bit whimpy when we're talking about modern laptops.  While they're adequate for the $500 Best Buy specials, we Mac users have come to expect a bit more for $1000+.  While still just dual-core, these new grinders have enough beef to handle all but the most demanding number crunching, like video encoding or 3D modeling.  Virtually everything else is quite doable.
3. Thunderbolt will make all things possible. OK, maybe I'm jumping the gun a little bit, but my mind just reels when I think about all the technology a bi-directional 10 gigabit connection makes possible. I imagine it won't be long before we see gigabit ethernet adapters, firewire hubs, external video cards and much more to go along with the already available super-fast storage devices. The old "lack of peripheral connectivity" argument no longer holds any water at all.

Any one of these improvements alone make a MacBook Air a very desireable machine, but taken together (especially in the 13" model) the Air could become a "MacBook Pro Killer".
