Couple of days left to pick up some decent software for about a tenner:

Little Snitch

VirusBarrier

Control Center

Speedy

Default Folder X

Parallels Access

Cocktail

uBar

TotalFinder

Postbox

CodeKit

Bought it, mainly for CodeKit initially but I've found Default Folder X incredibly useful. I already had TotalFinder and Little Snitch from previous bundles but they're both good. uBar looks very slick but having a start menu on Mac OS gives me a headache . Certainly got more than a tenner's worth out of it.

CodeKit is excellent, quite happy having paid full whack for it.

Couple of them look good, Speedy, Default Folder X, TotalFinder and Postbox stand out. Parallels Access looks interesting, but the same functionality is coming to Alfred shortly.

Just used parallels in anger at work to show my boss a movie file.
Left the Mac on while its virus checking my drives when I left the house, and over lunch ales him for some grading advice on someone's work - loaded up parallels on my phone and played the file back in VLC on my machine at home while we watched it over a coffee.
Impressed with it so far.
