The one techy/geeky thing I'm excited about these days is my Roku box. Streaming Netflix stuff is awesome (quite happy with the quality), but all the other channels too are a lot of fun. Leo Laporte's even got his own channel and Hulu is coming soon. Might be old news to some of you, but since I just "un-bundled" myself from cable/internet/phone - I'm happy with the cost savings and exposure to new 'channels' thanks to trying something like this out.
Can't say that modern "computing" is becoming any more fun for me, but I do plan on getting a multi-core Intel based Mac someday soon. At this point though, all I care about is how quickly I can get things done. How fast programs load, behave and how stable they are - that's all I expect anymore. The latest version of Safari, as quick as it is, crashes on my G5 often and when it does, takes several passes of clearing caches, cookies, etc. before I can re-launch it.
