I’m trying to find a good online task management system to replace my PlanPlus dependency.  I’ve been looking at the following…

Remember the Milk:  Well developed but the number of tasks I have would make this impossible to work with.

HiTask:  What beautiful design.  I love the look and feel.  It’s a little too basic though.

Nozbe:  I very, very powerful GTD base task system.  I like the mobile version and the iGoogle add-in.  It’s sort of ugly and hard to read though.

Backpack/Basecamp:  Tried them both.  They are just too much for what I want.  I’m not looking to set up a team on the system, just me.

PlanPlus Online:  Trying it now.  It’s close to the desktop version that I like but it’s so slow and it seems like yesterday’s coding.  (They need some AJAX or ruby on rails mojo or something.)

5PM:  I’m very impressed with this system but again the task subsystem is a little lacking.

Central Desktop:  Slow.  Clunky.  Not digging the tasks section.

I’m so close I can taste it on some of these but we’re still not there.  Does anybody know of any other good ones to try?
