On the web, Harvest Forecast [3] looked tempting, but I haven't dived into using it. I love Harvest for my solo time accounting though.
For solo projects, I really like Mr Schedule [4] and its keyboard driven outliner type interface (inspired by Joel Spolsky's Painless Software Schedules). It doesn't do resource management, so is unlikely to be helpful to you (but maybe to someone else here). Sadly it seems abandoned & requires Java, so I've been making my own cross-platform clone of it (just for my own use for now).
I tried ProjectLibre and it just felt horribly, horribly broken.
I wish someone would make a decent Android tablet app for project management, bonus points if it supported the Samsung Galaxy S-Pen for reordering tasks etc. I tried several Android apps & didn't find anything I liked.

Are you trying to track a team, or a single person? Do you want to use it to plan (at full project manager level) multiple projects, or do you just need to see where you're at with a handful of projects?
At here i don't even see trello.
