The lights are on
I would definitely recommend one. For $300 dollars you are getting a blu-ray player, internet browser, and a game console with incredible hardware. Also, there are more than a couple good games for it. There is Uncharted 2, Killzone 2, Infamous, LittleBigPlanet, Metal Gear Solid 4, Flower, Wipeout HD, God of War 1 2 and 3, and Demon's Souls, to mention a few, which are all great PS3 exclusives.
Also, you get an added benefit with PSN. You receive free online, and some truly innovative titles that would never see the light of day on XBLA. On the whole, there really isn't anything flawed with the PS3, and is totally worth the price, as you get too many features to count, for just 300 bucks.
