I have to hand it to ThinkFree, they certainly are a dedicated Mac developer. They catch a lot of flack for charging for their office suite, yet it's a pretty good alternative to MS Office (my chief complaint is the non-customizable toolbar... a must for laptop users). They provide a FREE online office docs repository & online office suite, which also allows the storage of other files up to 1GB of space. They now have this monitoring widget.
Say what you will, but they seemed dedicated and determined to win the Mac users' business.
