I ordered this Raspberry Pi kit as it had everything I wanted (the Pi itself, a power source that'd work, an SD card preloaded with an OS and that funky looking case) and nothing I already had and could use (HDMI cable from the blue ray player, keyboard and mouse from my PC and the TV has several HDMI ports), all for a decent price. Other kits either lacked something I wanted (the case, for example) and/or had other items I already had (keyboard, mouse, HDMI cable) and for a higher cost than this kit.
The only difference between my kit and the product description is the product description says that the SD card comes preloaded with the Debian Squeeze OS. Instead of this my SD card has the recently released NOOBS (New Out Of the Box Software) which consists of 6 (yes, six) different operating systems to choose from: Archlinux ARM; OpenELEC; Pidora; RaspBMC; Raspbian (the recommended OS which is a version of Debian for the Pi); and RiscOS. So instead of a single operating system, I've been given 6 (though, ultimately, they are variants of Linux and Unix). I've not chosen which Im going to use yet.
So this is definately worth the money and I look forward to playing with my Pi and seeing what I can make of it.
