Purchased a new laptop from
www.ibuypower.com a month ago or so, was recommended by a number of guildmates. Haven't had any issues so far, and I play WoW on it at home/work all the time, mainly dualboxing when at home. If I play full screen I get 30-40fps in IF, I usually play in windowed mode though and that drops my FPS in IF to about 20ish. Can raid with it just fine, haven't done Thaddius on it yet, but in most raids i'm getting 20-30fps windowed mode. Haven't had any issues so far, I'd recommend checking them out.
Total cost was $1350
LCD: 15.4, 1280x800 native, going bigger then a 15.4 really starts to cost you, and laptops are usually much closer then your desktop monitor, so the smaller size isn't as noticeable.
Processor: AMD TurionT64 MT-40 CPU [2.2GHz, 1MB Cache] w/Hyper Transport Technology
Memory: 1024MB [512MB X2] DDR-400 PC-3200 Corsair (you can get this as 1 stick of memory allowing you to upgrade later, costs $20 more?)
Video Card: Mobility 256MB ATI Radeon X1600 PCI-Express
Hard Drive: 100 GB 7200rpm ATA-100
CD-RW/DVD-RW Drive: 8X Dual Format DVD±R/±RW + CD-R/RW Drive

4x USB ports, s-video, etc.
