Hm.. It looks like a new version of my X61! I love this machine. Its actually sturdier build then a mac book pro. I have a power book g4, and everything has cracked on it: The screen, 2 times! both the usb ports, the track pad, the cd burner.. I loved it, and at the time I thought it was the best build laptop! last year I got a Lenovo, and ive never looked back. Its smaller then a macbook air, its got 3 usb ports, 1 firewire, 5 hour battery, all the wireless stuff, but most importantly: its built like a slim tank! what more, its go a handy keyboard light, and the keyboard will drain liquid if you spill on it! Also, the hard drive is super easy to change. I once changed my moms macbook drive, and it took me half a day! Insane. I know that some new mac laptops have fixed this.
Its been almost a year, and I haven't had a single problem so far. I run 2 systems though/dual boot. Keeping a pure safe system for live and studio use, which are never exposed to the net. Still, my net system runs with no problems at all. It cost me about the same as yours.
Its a great machine, enjoy it!
I recommend using Total Commander for your system file browsing. And as long as you don't install any dodgy crap, and stay on safe web pages, you'll be fine. Running XP, but looking forward to 7.
