First let me say that Launchy rocks. Simply the best keyboard launcher I've ever used (I don't have a Mac, so quicksilver isn't part of the competition). And version 2.0 was rewritten in Qt, slashing the code size and making it possible to have it on Linux/Mac as well (the author has mentioned this, but it is still quite a bit of work because of all the platform dependent code in the app).
As for the other apps, I grew out of that stuff several years ago. I really can't be bothered to install and then run a bunch of little utilities just to get basic features like resizing windows to a specific size, or snapping them to edges. All those kinds of nice little features come for free with any decent Linux window manager. I have better things to do than track down little utilities to hack that functionality onto Windows. I'd rather just do without.
3 out of those 5 apps work just as well on XP, one is a modification of XP tool, and just one can be described as Vista only (not that it's somehow unique/revolutionary)
Almost like they're inviting accusations of keeping quiet the fact that XP can also gain thanks to those apps
PS. It gets even better - one of those apps, according to its creator, has issues on Vista (thoough author of the article dismisses this...hm, who to believe? )

It's not tweakui, it's tweakvi They have 2 versions, a basic free version and the $50 one.
Well, I don't use Vista and have never heard of this tool until now. I haven't seen what all this can do, but from what I read in the article, I would agree that $50 seems a bit much for what it does. There's gotta be some free utils that do the same thing?

There are many more applications for Vista.
For instance Switcher (the Exposé clone): http://insentient.net/
It works only under Vista and shows live previews.
