Sony was vague about when PlayStation Now would reach PCs, but apparently you didn't have to wait long at all -- it's available today. If you have a sufficiently beefy Windows PC (a 3.5GHz Core i3 or better), you can stream PS3 games to your computer that include recent additions like Tomb Raider: GOTY Edition or Heavy Rain. You'll still need a fairly pricey subscription. You'll ideally want a DualShock 4 controller (either wired or through the $25 wireless adapter due in September) to play as well, although it's not strictly necessary -- an Xbox 360 gamepad is fine if you don't need Sixaxis support, for instance. As it is, Sony is sweetening the pot through a promo that gives you a year of PS Now for $100. That's inexpensive enough that it could be worth a shot, especially if you've never owned a PlayStation and want to see what the fuss is about.
