I'm doing some research to see what kinds of services people are willing to pay for and what about the service convinced you it was worth paying for. Links to said services appreciated.
Fogbugz, several VPS's (prgmr), Dropbox, Spam Filtering, Oreilly Safari, Lynda.com
Should be obvious but they're all required to do my job, the last two are more reference/learning. These are services I couldn't do my job without, that's what convinced me to pay for them. If you had to pay for Google Analytics I would.
Personally: Netflix, WoW, Audible, Last.fm (I live in Canada) simply because they are the _best_ (legal) source of entertainment (in my opinion) in their category.
http://crashplan.com - Easy unlimited backup. For all those things that don't fit in my dropbox folder. Also, it's the only service I found that had few bad reviews (unlike Mozy).
I would really like to pay for Github, but the private repo limitations are holding me back. I'd much rather pay $10-20/mo for unlimited private repos if it meant each collaborator also had to be on the same $10-20/mo plan. For now, my private projects are hosted for free at Bitbucket.
