I Heart GameTap. Earlier this month, I finally finished the first episode of Sam and Max and started on number two, and now I've finally found the quirky wonder of Typing of the Dead. I could have gotten this years ago for my Sega Dreamcast, but I never got the keyboard peripheral for it. However, playing it in high-res on a PC monitor with my ergonomic keyboard isn't too shabby, and it's about the most fun I've ever had with a typing game. The genre's been around forever (see Typo Attack for an early example), but it never was done with zombies. I think something like this would have been an awesome game for the Foleo. Astraware did a typing/Graffiti game called T-Blaster back in 2002... it's not as much of a challenge with the Treo and Centro keyboards, but add zombies, and you've got something special.
The other games that have taken a bit of my time are Picross DS (puzzle-solving crack that I've been working on since August) and the Legend of Zelda: The Phantom Hourglass (awesome touch-screen action-adventure that continues to introduce new and interesting kinds of interaction even 2/3rds of the way through the story). I Heart the Nintendo DS too.
BTW, it's not been all game playing... but I can't write about work right now, and I've been covering my travels through Twitter (and the repostings here). I'll have some pictures from my trip to Colorado up soon too.
