Microsoft joined the scene in November 2010, with its Kinect (previously announced under the working title "Project Natal" in June 2009).Unlike the other two systems (Play Station 3 and Wii), Kinect does not use controllers of any sort and makes the users the "controller." Having sold 8 million units in its first 60 days on the market, Kinect has claimed the Guinness World Record of being the "fastest selling consumer electronics device".

The days of having a slot-in memory cartridge are far gone – a few hundred gigabytes would be modest by today’s standards. Luckily, Sony made it really easy and user-serviceable to upgrade the internal storage drive – unlike Microsoft, who locked it down and demanded you buy first-party approved models only.If you opt for a 5400rpm drive, another spec you should see listed alongside capacity, you'll get similar performance to the standard PS3 HDD.Upgrade to a 7200rpm hard drive or a more expensive 2.5-inch SSD, though, and you'll see significantly improvements to load times.Upgrading your PS3 drive will not void the warranty.I recently bought a new PS3 Super Slim – the latest model – but it only came with a measly 12 GB flash storage.Something like the digital version of Uncharted 3 will eat up a huge chunk of an older PS3's HDD.It's very easy to upgrade the hard drive yourself though.
