Apps that cost $ (or are crippleware):
iBank
LicenseKeeper
Audio Hijack
SoundConvertor
The Missing Sync (major disappointment, see below)
1Passwd
SWF & FLV Player
Some of this is priced nicely ($10). Some, not (iBank @ $50). Considering some of the bugs and interface quirks I've found with iBank, I'd expect more out of a $50 program.
Don't get me wrong, there are also a lot of great freeware apps too. CyberDuck, QuickSilver (which I still haven't downloaded, I keep hearing it's a resource hog), NeoOffice, Acquisition (mild nagware), Adium, Transmission, ffmpegX, VLC, SuperDuper (very mild crippleware), MacTheRipper, Handbrake, and lots more.
The Missing Sync is a big disappointment at a whopping $50. Umm.. it's a sync program. I plug in my Windows Mobile phone, and it syncs calendar/contacts/etc. $50?! I refuse to buy it, I would rather just manually enter stuff twice, honestly.
Not to mention Toast 8 Titanium is overpriced at $80-$100 brand new. Yes, it's a great program and I bought it, and like it a lot. I actually got the upgrade price of $60 (a bit much for an upgrade price, honestly) but that's a long story. But Toast falls victim to the same problem Nero (Windows burning app) does. They throw in a bunch of extra stuff I'll never use, and hike up the price. Just give me a really solid CD/DVD burning app, that's it. The only reason I went with Toast over Disco is because I was told Toast was probably the best (only?) way to take any video format and burn it to a video DVD. If Mac had a program like DVDShrink for Windows, I would've skipped Toast and bought Disco.
