+1 for Pure Calendar Widget but yeah, 'tis not free. I also use SpareParts religiously to gauge my usage and battery life. I <3 Timeriffic. I use Astrid for tasks; it's by far the most feature packed task list, i just wish it synced to google tasks. NewsRob for RSS and Pandora for streaming. i use those apps pretty much everyday. I am currently trying out Handcent SMS but can't add it to the list yet, as i've only had it 1 day.
