Need 2009 WoW playable laptop shopping list

Can all you guys who play WoW on a laptop furnish their makes and model numbers for me? I have to replace my old, fried HP Compaq 1501CL which played it beautifully with beautiful graphics and sound but don't know how to compare specs and WoW (plus all extensions)requirements.
My Toshiba A205-5000 plays it very well except the sound started thudding after the 3.2 patch and I couldn't get it to quit stuttering so had to disable sound. I'm trying to compile a WoW Playable Laptop List for myself and the other thousands of shoppers who MUST have replacement laptops to play WoW.
