I'm thinking about getting a laptop for some CAD work on the go, but I'm not in a hurry to get one yet. Other than waiting for Penryn and LED backlit screens to become a bit more common, is there any other new tech around the corner worth holding out for a month or two? And has anyone seen a review comparing the LED to non-LED backlits back to back on the same model to see how much more battery life you get?
Oh and a few other noob questions (never bought a laptop before): Is there room for more than one HD without sacrificing any other components? And would replacing components yourself (CPU, RAM, HD, network card, etc) void the warranty? Finally, are the extended warranties worth it? When I eventually do get a laptop it'll most likely be thrown into my backpack along with my textbooks. Spills are not an issue though.
