as a PS3/Wii/PC gamer I agree about 95% with you DmeisterJ. I kinda like the channel interface, it's functional and looks friendly though it does get a bit cluttered if you get alot of channels. There is probably a way to organize it or move channels around, I've just never bothered looking.
Other than that I completely agree. The online component really sucks...hard, I loathe friend codes and that is the one thing that keeps me from playing SSBB religiously. The online is so awkward and terrible. The hard drive thing is a pain for some but honestly I've only used a little over half of my space and I've had my system for over a year. Most games I DL use very little room, but I don't get many wiiware or N64 games.
I have about 12 games on my wii and I love it to death. Even with my new PS3 which I got about a month ago, I still use my wii way more. It's a great little box and it deserves every bit of praise it gets.
