I’ve heard good things about that but under a different name. I think it was Windows Vista Service Pack 2.
It can be used as a direct upgrade to Vista .. and so, it got that name.
It also comes as a standalone OS which I installed onto a new drive in an old (read custom Pentium 4) PC which runs XP SP3 Pro otherwise.
For me, it benchmarked faster than XP and useability wise, faster and smoother than Vista on another machine I upgraded.
In terms of relevance to this thread .. it will be interesting to see how it translates for those who need Windows in a Mac; I don’t own an apple of any flavor so I can’t comment.
However, reading the comments of those who use XP in a Mac, I could suggest that the experience might be quite rewarding .. a “Mac-like” GUI with very fast windows under the hood.
Then there is IE 8 .... 😠
