UNIX grew up in an era when it was more important to be terse because keyboards weren't nearly so ergonomic and you didn't see more than 24 lines on screen and hard copy printouts were more common.
That and the fact that C at the time had a six-character limit for variable names.
You can play Guitar Hero DLC from an SD card, but yeah, I agree with you that this doesn't really sound like something that fits in with the Wii universe. Unlike the HD consoles, both of which set out to be media centers. When the Wii launched they were explicit that they did not want it to be one, which is why it doesn't play DVD movies even though it has a DVD drive.
Yes, CDE is still included in Solaris (as of version 9, but I'd be surprised if 10 didn't have it), including the free version of Solaris Intel. Gnome is the default, but it's there for anyone who's feeling nostalgic.

The rev command has got to be one of the most useless Unix commands I've ever come across. It's almost as if someone's first c program somehow got taken up as a part of standard Unix! Maybe in the days before sed and awk and perl it had some function in pipes that I can't grok, but nowadays other than making hints for video game websites I can't imagine what it's for.
