(a) 1920x1200 in a 15" machine
(c) A ton of memory
(d) Reasonably good performance and battery life
(e) Sufficiently "decked out" that I won't regret not having some feature a year from now
(f) Not Sony
(f) is easy to do. (c), (d), and (e) are basically just configuration options, and (c) and (d) are necessary for Photoshop. (b) seems to be more or less standard. That brings me to (a), which is the real kicker and an absolute requirement.
Dell has two models that can be made to work-- the Studio 15, and the M1530. The former is cheaper, but appears to be more cheaply made, while the latter is the business workhorse. The difference is around $700. I haven't looked at other brands, but shopping by screen resolution seems ridiculously difficult.
Sadly, I seem to have missed the market for getting XP. I'm either going to be stuck with Vista, or I'll install XP after I get it.
Anyone have recommendations?
