The iPhone 5 is set for a general public release in two days time, and overnight, we have started to see some reviews being published from those who were lucky enough to get their hands on the review and testing units. The reviews are obviously a great resource for people who are considering exchanging their hard earned cash for an iPhone 5, but there will also be a lot of people who are wondering about the actual performance of the device when using it in a real-world environment for everyday tasks.

If your computer usage requires as much processing power as you can get, one of the factors that might be holding you back from upgrading to OS X Lion might be a possible performance drop. It now turns out that both Snow Leopard and Lion perform similarly on the same hardware, with irrelevant variations that should not greatly impact performance, for good or worse.
