Software Fun
Set up Synergy for some cross platform Keyboard/Mouse sharing so I have the iMac sitting next to my two other panels.
I don't know how I ever survived without Evernote, I used to dump a bunch of files to my desktop, random stuff gathered mostly from the Internet, not knowing exactly where to file all this stuff. Now, I simply dump it all into Evernote and let its auto-indexing do the work so when I'm looking for something, all I need to do is search and it will find as I type. It'll even use OCR to search text within photographs and images so I can snap a photo of a receipt and find it later by the contents of the photo!
