I'm looking at recent software with a radical new layout on my XP machine. Recently I acquired Ranking Toolbox 6 and Hello Engines 6 from a deal with my web hosting provider. And I just now am trying the new version of Nitro PDF Professional.

These 3 applications are running on my beloved XP machine with that ugly, confusing, resource and screen real estate hog Vista layout. It's just unbearable that thing. Some may like it, I can understand that. But I don't.

So... what is going on?
- Is this thing switchable?
- Can I expect my sweet XP machine to slowly become crowded with this crap?
- Where is the closest Linux distro?
