Cheap PS3 Keyboard But Perfect
works perfect 4 the ps3 !!! You need this thats all I can say , Also you need A keyboard to install linux.

o.k.
This does have a cord it's not cordless. It's also not as useful as I thought it would be.

Playstation 3 USB Keyboard
the key board is nice for PS Home for chating "or fighting with those every so many pricks" it is the size of a reg key board very smooth typing its better than the one im using right now on my pc to right this lol the only down side to this key board is that it has a wire it would be alot better if it was wireless but hey what can i say i only paid for mine and it is way worth it

Useful for Basic Text Chat
Well what can I say beyond the fact that this particular model of keyboard is useful in basic text chat upon the Playstation 3 and its Playstation Network? Though it's a bit bulky considering that one is transitioning from the six axis / dualshock 3 controller to a PC worthy keyboard and something to get used to, but once it is done, one will be glad that you no longer have to use the time consuming controller-based text board.

Really just a plain ol' keyboard
Pros:
-Durable
-Long cord (8 feet)
-You know it will work with your PS3
-Price

Cons:
-Plain design (but at least it's black)
-An included palm rest would have been nice
-No included instructions on what keys do what (check out the PS3 manual at the official PlayStation website for some internet browser keyboard shortcuts [Support->Manuals->PS3->System Software User's Guide])

Notes:
-You will still need to use a PS3 controller to use certain functions, as far as I can tell
-This might be obvious, but you can also use a USB mouse with PS3
-Now that I have a keyboard, I've been able to install and mess with Linux on my PS3. Try it, it's fun (but also frustrating).
