I usually pride myself on keeping up with computer stuff, but boy did I miss the boat on this until now. Why did no one tell me?
Anyway, I found Webguide today. I had been wanting a Slingbox for a long time, and should have thought to look for a free solution, especially since I have a PC with Vista Ultimate and a TV card. Webguide is what Slingbox is, only free. Created by a dude that now works for MS on Media Center stuff.
If you have a version of Media Center, you can download it and the setup is easy.
I'm also partial to Piclens these days for another add on that's free and worth it. Lemme know if I'm missing out on other cool stuff from now on please.
There's nothing that screams to me "must get immediately". Time Machine looks pretty cool, but I'm a little nervous about my co-workers abusing that feature to the point of frustration (for me, that is).
