Windows 7

Bring back windows 95

[chef]

have been running win 7 since RC1 and haven't had any issues. Have it installed on my main business laptop and have just this weekend upgraded it to a legit retail copy. It's far far better than vista, it just simply works IMO.

MS DOS 5.0 was the best...

Digital Research's DR DOS 6.2 with the inclusion of DELTREE was without doubt the best!

TBH ... Window's NT/2000 was the last one I really liked. Have came round to XP as it's improved ... Vista spent a whole 2 hours on my laptop before it was burned!

Setting fire to your laptop seems a bit extreme

Pah, who needs DELTREE when you had Norton Commander 3.0?

I thought the OS-X kernel had its origins in the BSD kernel. I think the original multitasking Windows kernel is also based on the BSD kernel.

OS X uses the Mach kernel. Here and here.

OS is not just the Kernel: GNU Linux for example, new Kernel but lots of stuff from GNU, all together one OS - separately not useable (certainly not kernel), same for Windows - kernel is a very small part, the real meat around is what makes it an OS.

HTH

One thing I love to do is grab my bar and give it a good shake. Talking about Windows 7 UI enhancements of course.
