Oh you lucky lucky man... I'd kill to have the cash to buy a decent laptop at this point... (I'd totally use it for photography and "off site" development)
Sounds like you guys have quite the setup now; I'm so jealous lol...
How are you liking W7? I hear some people are having issues with the learning curve, coming from WXP.
Myself I got stuck with having to use vista with such a beefy setup (2.6ghz quad core machine with 4gb ram; XP wouldn't give me nearly as much bang than vista would). I recently upgraded to W7 64 Bit and am loving it (I highly recommend the 64 bit version if your hardware supports it)
