Thought I'd share a little about two tools that help keep my computing life sane. I regularly work on 3 different PCs - my development box at work, my home PC and my notebook, and I need a few things to be consistent across all of them.

Bookmarks

Like a lot of people, my bookmarks have become an extension of my brain. I don't pay attention to a site's Url, I just remember where I filed the bookmark. So it's really important to me that all 3 systems have the same bookmarks, and that they all update each other. I'll also note that I've also become totally addicted to the FireFox Bookmark toolbar. Having all my bookmarks easily available in folders across the top of the browser is very efficient.

 When I used to use IE, I would create folders below Favorites\Links and get the same sort of functionality.  

But, to the point of this - FoxMarks is a FireFox add-in that facilitates synchronization of your FireFox bookmarks across multiple machines. It's super simple to  use, and it just works. Get it. Use it. Love it. 

File Synchronization

While I don't need everything synched up all the time, I regularly need files moved between all three systems - particularly presentations. Foldershare solves this problem really elegantly. You have to install a small program that runs on each PC and connects across the net to securely synch pre-determined folders. The synchronization is real-time while you are connected. If you go offline for a while, it will automatically re-synch as soon as you re-connect.

Additionally, you can access the shared files from any web browser by simply logging into the FolderShare site - a nice feature (although I've never used it), and a good reason to use a strong password!

Although you can share whatever folders you want, I try to keep this simple, I just create a "Shared Desktop" folder on my desktop. Anything I want replicated I just drop in there. This is sooooooo much easier than toting things around on USB memory sticks etc. I'll also mention that Microsoft bought FolderShare and thus this is now a "Windows Live service". And it's in "beta".
