"Light weight and lightning fast"5.0 starson by tlackner
Pros: Weighs little, does everything, very fast, good display, great battery life
Cons: Only 2 USB ports, keyboard not illuminated
Summary: I've been using "portable" computers since the original Compaq luggable PC. The MacBook Air finally seems to be the answer. First, it's light. That, of course, is achieved at the cost of things like a built-in DVD drive, so you wind up carrying some peripherals: for me, that's a superdrive, a 2-button bluetooth mouse, a couple of video adaptors, an ethernet adaptor ... But I put my bag on the scale the other day and even with power supply, pens, pad, etc., it comes in at less than 5 lbs. That's a long way from the 9 lbs my old MacBook Pro weighs. And that is a big deal when you're standing in endless airport security lines.
The battery life is phenomenal. It handles transatlantic flights effortlessly, although if you're working on graphic files or watching a couple of movies you'll want to add the magpower adaptor (assuming your seat has power).
The full size keyboard is a nice feature. The PC netbooks are hard for people like me (short, pudgy fingers) to use. And, speaking of PC netbooks and laptops, the MacBook Air has other strong advantages over them. One is that this is a computer, not a computer wannabe. It handles all my needs and runs all the software effortlessly, without resorting to stripped-down versions of MS Office and similar software. And, it does these things quickly. It is faster than my MacBook Pro or my PC tower, and far faster than my 15 month old PC netbook or my 3 year old PC laptop.
PC laptops and netbooks all come with another disadvantage: the jumping cursor. You're typing away and suddenly notice that the cursor isn't where it's supposed to be. Instead, it has gone back several paragraphs - or pages. This seems to be a problem endemic to PCs, because every PC laptop and netbook I've used has suffered from it. Not so with the MacBook (Air or Pro). Cursors go where you tell them, and stay there. Think about the difference between a puppy (PC) and a well-trained dog (MacBook).
The display is stunning. No other word for it. It's as good as a free-standing monitor, although you'll want a larger separate monitor if you plan to use the MacBook Air as an office machine.
Disadvantages: relatively small storage space (hence the superdrive) and only 2 USB ports for all those peripherals you're carrying plus the flash drive someone at the meeting wants to plug in. Four-port USB hubs are small and lightweight, and I carry one of them right beside my mini-powerstrip. You don't have a travel powerstrip? Maybe the best single investment I ever made. Now I don't have to move the furniture in half the hotel rooms I stay in. But these weigh little, and certainly weigh less than building them into the computer.
In short, it's only taken 25 years for me to find what I wanted: a full-featured, truly portable computer. At last, I'm the one who's envied in the coffee shops and security lines. And, from the boss's perspective, my productivity on the road is the same as in the office. Although maybe that isn't such a good thing.
