Edit: It seems that the publish call didn’t go through all the way so I am publishing it again.

As a contractor I spend a lot of time working on projects other than my own. To keep track of the things I need to do for each project as well as University classes I have been using Things recently. Both Things Mac and Things iPhone have greatly helped in keeping me organized between my work, client work, and University classes. Not to mention home. The price is a little steep for both of them. I don’t really know if it was worth the entire $60 since there is no push feature. I am confident from CulturedCode’s awesome status page that the features will actually come out so I considered it a future purchase.
For time tracking I am currently using Billings and Billings Touch, together both are fairly expensive as well $55, if you want to be able to sync between them. I tried a couple different web based apps as well as a couple other Mac
specific apps for time tracking but the rest were not as comfortable or powerful enough for me to use. Billings takes a second to configure and isn’t very intuitive slips can be marked as done but when a project over laps a month it doesn’t really seem to be useful.

All in all Things and Billings are just the apps I have been looking for to help manage my time and task list.
