Hi Mike,
We have 3 PCs and they are running XP. At my wife's job and at our Library, which has about 12 PCs, they all use XP. I haven't seen a Vista computer yet in person. It seems like most people here just skipped Vista.
We got our last PC 2 weeks before Vista came out and I was happy later that I missed it.

My wife had a couple of classes for work related training and they used new Gateway Laptops running Windows 7.
I asked her how Win7 was. She said she didn't even notice. She loved it. She came home wanting a brand new Gateway Laptop though. I don't blame her. What she uses at work is older and cheaper than what we have at home.

She uses a 22" widescreen monitor at home, which helps with her eyesight, yet the brightness and clarity of the 15" Laptop display blew her away. She said she never saw anything so bright and clear. She emailed the instructor and he said they were LED displays, not LCD. I never saw one. Ours are all LCDs.

I'm glad that the next PC we get will be Win7. Maybe by then it will be Win8.

Wayne,
