After sending back my new MBP (I'm keeping my old one), I'm curious what alternatives there are out there. I've seen people recommend various HP and Lenovos. What I'm looking for: * Mid-range graphics performance. I'm not expecting nor wanting top of the line. However, I don't want integrated either. * 15" screen. Not looking for an ultraportable or luggable. * Reasonable weight. Something in the 6 lb range is good. * Reasonable storage. 250 GB HD. Blu-ray would be a plus. * I don't need something that'll win design awards, but I'd prefer something that wasn't flimsy plastic either. * Windows XP-able. I don't plan on using Vista. Is there anything out there similar to MBP in specs (although perhaps not design), reasonable weight and around the same price? (Yes, I know I won't be getting OS X. However, I have OS X on my main machine, a new aluminum iMac, and I don't mind having different OSes in my home).
