I just purchased a Microsoft Natural Ergonomic Keyboard 4000
I paid 52.69(sticker 66.00 then 15% off) I see Amazon.com has it
for 49.99 I guess I didn't do so good. Even as they go out of business they still manage to rip me off. However all hope is not lost during my Amazon prize search I noticed Microsoft has a rebate, turns out buying it from CompUSA keeps me qualified for a 20 dollar rebate. so I end up paying a little more for having it today.
I have always been a fan of Microsoft's Natural Elite keyboards and this one does not disappoint. The F Lock is enabled by default and will remember its state between reboots its USB ( my computers don't have ps2 anymore). Best of all the home keys are not all jacked up.( I have to get used to a small delete key again).
As a side note the drivers that come in the box's cd will not install under Windows Vista but you can install IntelliType Pro 6.1 to get it to work.
