I'm not a huge gamer, but I bought a Wii. I have to say it’s a fun little system, especially coming home from work and putting on Mortal Kombat.
As far as Sony's PS3 I cannot comment on the unit itself.
However, I lost a great deal of respect for Sony themselves. The only reason they dropped the price on there "basic" unit was that they had too many and had to get rid of excess inventory. That just does not sit real well for me. I understand it was a business decision, but it sends mixed signals for sure.
