Is there anything you have purchased recently that's been around for a while, and makes you wonder why you didn't buy it earlier?

For me it would have to be a mini system that I purchased for my room. It's plays MP3's and CD-RW's. I've had it for like 4 months now and have only needed 1 cd since it plays re-recordable cd's and I can stuff a crap load of songs as mp3's.
