Alternative to the meta key

I use and love my Unicomp Classic 101. When I bought it I was primarily using Linux and didn't see the need to have a Windows (also known as meta, super, that-one-between-ctrl+alt, etc). Since moving to mostly Windows 7 though, I've noticed that there is functionality built around that key. I believe this is increasingly showing up in Linux window managers as well. If any of you are in the same boat as me, fear not! In Windows 7 ctrl-esc provides the same functionality!

Microsoft Security Essentials

I never thought I'd find myself recommending a product from Microsoft, but Microsoft Security Essentials billed as "The anti-annoying, anti-expensive, anti-virus program" rocks. Free for up to 10 computers this thing lives up to those claims. Since there's no "premium" version unlike almost every other Windows antivirus, there's no need for nagging, or ads. The updates are smooth and require no user intervention, unlike a particular open-source windows av. MSE also provides real-time protection which in some similar products is a premium feature. I really haven't found anything to dislike about this product just yet, and I will certainly be installing it on the computers of everyone for whom I end up providing pro-bono tech support.
