By the new style do you mean Yosemite? My Mac keeps asking me whether to update to Yosemite and I keep putting it off in part because I’m not sure whether I’ll like the new look (haven’t seen enough to decide either way).
And I can’t upgrade to Mavericks because Apple does not support USB monitors properly, much less Yosemite.
Pity, if it was Microsoft the $hit would hit the fan...
I mean Jon Ive doing the redesign of iOS 7 to dispense with “Skeuomorphism” ...

Of course we’re on iOS 8 now, so this was already started quite a while back (with iOS 7) and polished off more with iOS 8 (now).
