I’ve been on the lookout for good todo list software for a while now. My primary machine is a Mac, but I also use Linux and Windows and these days an iPod Touch has taken over most of the duties of a laptop when I’m out and about. Since it’s my main machine I looked first for Mac software and tried Omnifocus (powerful, complicated, expensive) and the Things (simple, brilliant, pretty, great support) but quickly realised that none of the standard solutions were really cross platform. Certainly none of them had the ability to sync from Mac to Linux. I could sync from desktop to iPod/iPhone, and Mac to Mac (sorta, using Dropbox), but Windows and Linux might as well not exist.
Then I discovered Tasque, which is an underdeveloped free application from the Linux-centric Gnome desktop. Tasque is simple and straightforward and runs on Linux, Windows, and Mac OS X. It isn’t pretty and isn’t especially Mac-like, but its killer feature is that it syncs with the web-based todo list Remember The Milk. So Tasque, plus a $25 per year Remember The Milk Pro account and free iPhone app (there are apps for other handhelds, including Android and Blackberry) means I can sync my todos across platforms and across computers; there’s always Remember The Milk on the web too. Despite its lack of shiny shiny I find Tasque works very well on my Mac with very little fuss.
