Picasa

Something I'm going to try - Google's Picasa. I just downloaded it after reading about it for a while. I'll let you all know how it goes, although unfortunately I will not be able to utilize all of its features as I am not connected with high-speed Internet here at home, so everything I would try to do online would be a pain in the ass.

Other recommended software (all free!):
Mozilla Firefox (makes IE look stupid)
ObjectDock
WindowsBlinds
