I'm a converted Xbox user, and I'm stoked to get into all the games I've missed. Infamous 2, Heavy Rain, MGS, Last of Us, etc. I think the collection of exclusives is peerless - Sony definitely delivered.
THAT BEING SAID...
I totally understand why people have a love/hate relationship with the PS3.
The super slim version that I got looks and feels awful - far more cheap than I ever imagined. The tradeoff for the 500gb harddrive at $300 I'm sure. I also got the whole box home and open before realizing I needed to go and get an HDMI cable. Not a huge deal, but it does seem a little crazy at this stage in the game.
The controller continues to suck, but I remain beyond psyched for the new dual shock. The fast charge, low weight and long battery life are great, but the triggers feel hilariously bad, and it carries over the somewhat cheap feeling of the console itself.
The interface and speed of the ecosystem are also troubled - things you take for granted with Xbox. Downloading in background has been giving me problems, everything seems hitchy and slow and generally just bothersome to navigate. But PS+ is a vastly better value than XBL and its very satisfying to throw free things onto your harddrive with abandon.
All things considered, I can see why Microsoft was able to gain ground this last generation and why Sony had to do a bit of an apology tour to set the table for the PS4. It's a fine gameplaying machine, but I do see a massive difference in style, flow and feel between the aging PS3 and the Vita. I think it's a sign Sony is heading in the right direction for the coming generation. I would be curious to see what kind of a corporate culture change there has been since the PS3 design.
All in all, very glad I bought it and I feel like I got a good value - but I do see the flaws and where Sony can easily improve. What a difference a generation makes (hopefully)
