I looks good nice thread btw.

Looks good to me.

Okay, but messy.

• PS1 should be first model.
• Delete the "no console" thing.
• Add more game consoles. You're missing a lot.
• There are other mistakes that should be corrected. 

Look here:

http://en.wikipedia.org/wiki/List_of_video_game_consoles 

The second generation had over a dozen consoles and Nintendo didn't really enter the console portion of the market until the third generation. I should know; I just wrote a research paper about the video game crash.

Its a good simplistic view of everything.  I use simplistic because it omits a large number of companies.  within the simplistic scope the main flaw is the absence of the horrible nintendo virtual boy from the portables section. 

From the greater perspective omissions from the handhelds include the microvision, GP32, GP2x, wonderswan, wonderswan colour, swan crystal, neo geo, neo geo colour, gamate, watara supervision, etc im to lazy to go further as there are lots.

omissions from home consoles are you know what i'm too lazy to finish http://en.wikipedia.org/wiki/List_of_video_game_consoles

I wholeheartedly endorse the simplistic approach beause the whole point of view just gets messy in the end 

nice!!!
grr....
sony took down sega!!!!
grr...
*sonic explodes

Interesting that handheld is on fourth gen and console 7th.

EDIT: I added in a couple of things, hope it's an improvement! :)
