I bought my 7762 secondhand a couple of years ago. Upgraded it to 6gb ram and a Samsung 840 Pro SSD w/ Middleton bios, and got a new 8-cell battery off E-bay. With Windows 7 64-bit and an Adblocker extension in Chrome, it works perfectly for all my office needs. I've got a 4:3 screen, a a solid laptop, and a proper keyboard.
Just took it apart yesterday and replaced the fan, as it was dying. With a few tweaks, I expect it to use it for the next couple of years as well.
The only thing I am missing sometimes is a brigther screen, so that I would also be able to properly work outside in summer as well, but as far as I can tell, my monitor is a 185 nits monitor, so it doesn't get much better than this
