I'm going to undergo writing a massive article that encompasses everything great and interesting about Gamecube. Please post things you think are important to include in it. Please write whether it should be a new section (I, II) or a subsection (1,2,3,4). Also, if you can think of a better way to order sections let me know.

What I have in mind so far:
I. The System
1. The console
-aesthetics
-system specs
-Controller (+gba controller)
-accessories (gba player, broadband, etc)
2. Launch
-Launch date and launch games
3. Prototypes?
-early console and controller

II. The Games
1. The Big 3 (Mario, Metroid, and Zelda)
2. Resident Evil franchise (The mature franchise)
3. The Capcom 5 (Viewtiful Joe, Dead Phoenix, killer7, PN03, Resident Evil 4)
4. Exclusive games that made the system (i.e. F-Zero GX, Eternal Darkness, Cubivore, etc.)
5. Third Party Support
-Tri-Force Arcade (Nintendo, Sega, Namco)
-Using Nintendo characters in 3rd party games (Mario in EA games, Link in SC2)
-Third parties (i.e. Konami) giving Nintendo the shaft.

III. Perception, Marketing, and The Community
1. The Press
-kiddie
-teh doomed and third party (started by the EGM rumormill iirc)
2. Marketing Campaigns & Community
-Born to Play, Who Are You?, Too Much Fun
-Lake Hyrule Summer Camp
-Reggie
3. Playing it Safe (sticking to heavy to franchises to make sales)
4. All Gamecube bundles
-Metroid Prime bundle, special edition Cubes, etc.

IV. The Competition
1. Nintendo versus Sony versus Microsoft
-Sales numbers
-Microsoft buying up Nintendo stock forcing Nintendo to buy up more of their own
2. Metroid Prime 2 versus Halo 2 marketing campaign
3. Rare's departure

V. Conclusion
1. The Death of Gamecube
-Total Sales
-Total Money Made

The Gamecube Years:

It came, it delivered Smash Brothers Melee, it hyped GBA connectivity as the next big thing against all common sense, it finished 3rd in that generation's console wars and in the final year or two, suffered from the same 3rd party game shortage that the N64 did (and without the cartridge excuse the N64 had).

Short version.

Purple.

You know, I know people would tell me otherwise, but outside of wanting Tales of Symphonia and Twin Snakes I haven't found a reason to actually buy a Gamecube.

Wii minus motion controls.

Dreamcast mkII.

The console that first brought Ikaruga to gamers outside of Japan deserves mad props.

My favorite console of that generation and still one of my favorites of all time.  Screw the haters.

Easy to play import games on, because it required no modding!

Gave me Resident Evil 4 and Metroid Prime, two of the best games I played during last decade.
