For Mac users wanting to upgrade to Mac OSX Lion, buy the OS X Lion USB Thumb Drive, and no huge download is needed. When Mac OSX Lion, the latest generation operating system for Mac was launched, users could download Mac OSX Lion from the Apple app store for $29.99 only. But remember if you agree to the payment, you should also be willing to download the huge 3.53 GB file!
OS X Lion USB Thumb Drive
OS X Lion USB Thumb Drive is a good option if you are on a slow internet connection with limited data limits. But it will cost $69, which is much more than the OSX Lion download from the app store. This Mac software on a USB drive is a good alternative which has been made available right now from the Apple store, though at a higher price. It is thin, has a nice Apple logo and can easily be added to your keychain.
Remember that to upgrade your Mac to OS X Lion, you must be running OS X Snow Leopard. If you run the older version of OS X v10.5 Leopard, then you need to buy OS X v10.6 Snow Leopard and install it on your Mac, before you get the OS X Lion. Your Mac must have an Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion.
