Don't forget that XP, W2K, 2K3, etc are the same way. That's not the issue for not buying Windows 7. You asked what I would like to see in Windows and I gave you
one example.
As far as better, that's
opinion. What's better for you may not be necessarily what's better for Joe Shmo. A statement like "Windows 7 is more secure than any previous Windows" is probably fact but lets not go overboard. Over at msfn.org there's a very lively section for the 9X kernel. They are of the opinion that it's the best OS MS ever made. For me, I cant live with the constant slowdowns and crashes in 9x but whatever floats their boat.
No, I mean't technically better. That's not opinion. From the standpoint of an operating system, the 6.0 kernel is a better OS. Now, I will agree that saying the look and feel of the GUI is better is definitely an opinion. I'm not a user interface guru type person, so I'll defer to experts in that realm.
Also, if the hardware you are looking to run the OS on does not meet the minimum requirements of Vista/Win 7, then yes, XP is a better OS. That too is not an opinion, but fact

. Kernel 6+ makes better use of memory, has a better scheduler, has better power consumption logic, makes better use of current video hardware, has a better network stack and even the file system NTFS has been upgraded. The only area that my have gone backwards is audio abilities. I'm not a sound guru, so i don't the specifics, but my understaning is that some of the blocks that the new kernel puts on audio hardware access may be exessive.
Also, if you are using a software package that only runs on XP, then XP is by far the best choice for you.
Barring those few examples, I can't see any reason why someone building a new system using current average specs (Core2 Duo/Quad 2+ gHz, 4 GB RAM, DX10 video) would choose to install XP. You are just not getting all you can get out of that hardware.
