I like to get things done. I also absolutely have to keep lists of these things. At college I used to have a list presented to me every time I logged into the UNIX mainframe. From there I moved on to various PDAs, such as the Palm IIIx. These days I mostly use equipment running iOS or OS X so consequently I want solutions that synchronize between all of those devices. I’ve read quite a few reviews of all the major offerings, but never found one that gave the answers that I wanted. Several of the reviews just contained marketing material and little of substance. So I’ve been spending quite a lot of time and money to test the applications myself. If you’re in the market for a to-do app, you could do worse than reading this short review of Things, Todo Cloud, Wunderlist and Omnifocus.
