It was only a month ago that Adobe cut off Linux's AIR, so bloggers may be excused if they were a bit surprised by last week's news. Namely? In yet another twist in the company's on-again/off-again relationship with our favorite open source operating system -- a roller-coaster ride that involved taking away 64-bit Flash for Linux last year -- Adobe has now apparently seen fit to bring it back again. Don't look now, but those neck pains you feel just may be whiplash, and you're not the only one.
