Which Of These Consoles Is The Best?
Sales
If you are looking into sales alone then the Wii outsells everything. However from my opinion (a person who has owned all of the Nintendo Consoles) this has been the worse console that Nintendo have ever made. So why is this?
The major reason why is simply because they do not give a damn about all of the past fans that made them money before the Wii, the majority of new games are aimed at idiots and Nintendo fans rarely see the light of day. Mario Kart Wii was at best disappointing as they seemed to take out everything that made Double Dash good. As well as this they are copying Mario Galaxy by adding in a few variations to levels in Mario Galaxy 2.
So as you can see the Wii is out of it.
Online and other
It has to be said that the PS3 is a great console with games such as Uncharted 2 it cannot be argued that it has some great graphics. The online although it is free it is very poor and you always find yourself in a game with people unable to speak English. I still do not know why language filters are not in there? Sure the PS3 has Blu-Ray but that seems to be all that it has going for it.
The Xbox 360 has the better games, the better online service and just a generally better experience overall. Although the Wii is an okay console it can get very boring very quickly. Get a 360 or PS3.
To make sure these will not have to be replaced for some serious money, get game console insurance or gadget insurance. Of course you could also get some mobile phone insurance while you are at it.
