Unless you need every speed bump for professional reasons there is no need to get the Corei7. The difference is too small to be noticed. For whatever the 2,4Ghz is too slow the 2,66 is too and only a desktop Lynnfield Quad Core helps.
The difference in SSD speed you can feel in general performance. It doesn't help with maximum Performance though. The really demanding jobs (games, encoding) don't run faster just the less demanding jobs (opening a program, copying files on the same drive) is a lot faster. An SSD is a nice to have upgrade but it doesn't enable you too do anything you couldn't before. I still think it is too expensive for what it is worth. IMO it still needs to come down in price, especially since I cannot deal with a drive smaller than 256GB and I don't want to put in a superdrive bay hdd.
I would always get the AG screen. Yes some people say they don't care about glare, but if you use it indoors at a reasonable brightness and watch
hulu or some movie or pictures, all stuff that can be darker and has dark backgrounds, I think the reflections are annoying. An AG screen is simply perfect in any condition and well worth the money. Also I wouldn't buy anything but HR.
