We have some old Dell Latitude D820 & D830 business laptops at work that have 16:10 aspect (1920x1200) screens on them.
(The high-res panel was an upgrade option).
Pretty nice machines for their time (around 5-6 yrs old now).
You can often pick them up these days for well under $300 - OFF LEASE or REFURBISHED.
Nice machines if you don't need something too crazy. They are very well built and have good spec's for their time (Core 2 Duo, 2GB Memory etc....)
It wouldn't be a stretch to throw an SSD in along with a copy of Windows 7 in one of these machines.
The trick with those Latitudes will be finding one with the 1920x1200 res screen.
They are around... just not as many compared to the lower-res versions.
Check eBay, or do a general Google search for them.
I doubt you'll find any new ones, but they are so well built that getting an Off Lease unit won't be a bad thing. If you can get one locally so you can see its condition first - That's even better.
Replacement Dell batteries and 90w power supplies for these laptops are pretty common, so if you need one it shouldn't be too hard to find.
