Hmm. In order to view CNN video archive, you now have to sign up for RealOne. I guess I won't be viewing any more CNN video archive... Real Player just plain blows.. (before I gave up on it in disgust, every time I'd start it up to play something it always told me I needed some update or another to view whatever it was I wanted to watch. Annoying as hell.. )
WMP 7 and above suck as well. They seem to offer zero functionality over WMP 6.4, but add increased bloat, lame-ass GUI, and it bogs down into a tar-filled pit of slowness. I installed the DivX codecs, and WMP 6.4 works great.
Here's one I haven't seen mentioned: Microsoft Word. Why does everyone feel the need to send me a 200k Word ".doc" file when they can just send the same thing as a 1k text ".txt" file? Notepad opens up in about 2 seconds and takes practically zero system resources, while Word... (and hey, there's always Wordpad if you need to do funky formatting..)
