I had a pretty good time playing Team Fortress 2 for a little while tonight, and while I was doing it I played a bit with the beta for the new Steam UI. It looks positively gorgeous, but god it runs like trash on my PC.
Sabriena and I are planning on buying new computers sometime in the next two years if our finances keep going the way they have been – our poor desktops are rather tired, and we may just end up picking up a couple of mid-range laptops to keep us going in the mean time unless we suddenly become made of money. I’m figuring we’ll aim for something with a Core2 processor and whatever’s cheapest with a gaming-capable graphics card.
Steam had a free weekend a while back for the multiplayer portion of MW2, so I figured I’d give it a shot despite the fact I have it for PS3 – a new group of people to play with might be fun, I thought… well, even though I’ve still stolen Sabriena’s DX9 graphics card, it doesn’t support Pixel Shaders 3.0. 
The Mumble developers are looking for someone who owns the Steam copy of Battlefield: Bad Company 2 to hack the offsets for positional audio, which at the time of writing only works for the retail boxed version and not for the Steam version (different builds, so different offsets)… same thing again, my PC just won’t run it so it’s not even worth looking at (besides, I already beat it for PS3).
Sometimes I wish we could just hit the lottery, but then I remember we don’t play it.
