MacUpdate has a software bundle up with 10 apps for less than the retail price of a single app! A la the much-disputed MacHeist. The MU bundle may be worth it for the $20 break on my new fave virtualization software : Parallels 5.
Also, i played with HyperSpaces and it is an essential add-on to OS Xs Spaces feature, though sadly, it costs dollar$. Now you could snag it for fewr dollar$.
As for the rest, i don’t see myself using them, but maybe you might?…
