If you plan to be typing, try to test-drive the keyboard - at a store, or if a friend owns one.
Do not stress about brand reliability ratings - you would be very unlucky to get a bad machine from a major manufacturer.
If you will be carrying this around with you, are you sure you want such a big machine? (If it will be sitting on your desk, of course that's fine.)
AMD's advice is the best. --BY the time most reliability ratings are out, manufacturers have stopped making the models the reliability ratings are based on. You would indeed be very lucky to get a bad unit from any manufacturer.
One of my good friends runs the repair center for one of the biggest tech companies in the USA. I've talked brands with him on laptops for over a decade. We talk this stuff 3-4 times a year. His opinion changes all the time. Every company has "sucked" at some point with a bad run, or a tough design to repair.
I've owned all the major brands. In every class. Desktop replacement sized laptop, to net book, tablet.
I used to swear by Toshiba. Got seduced by a Sony, and tho many people talked negative about Sony cos of the extra cost...it served me longer than anything else.
In your price range I'd go with an Asus or a Toshiba. Dell...heard too many horror stories.
To add irony, I type this from my first Mac. Wanted something superlight...and Macbook Air is sweetly designed By buddy and I both morphed from PC's to Macs full time in the past year.
Another buddy of mine is a corporate evangelist form Microsoft, recently for Windows 8. So I got to play around with Windows 8 a year go, and contrary to the lukewarm reception and shock to some people, I thought it was revolutionary and really cool. At a developer fete in Santa Clara, the developers were all loving it.
As for processors, I used to be up on all things AMD, but not in the past few years.
I am really impressed with the current intel series, think the finally solved the glut of confusion they had with too many classes of processors. Get a core i5 at least, and at least 4 gigs of ram.
