I actually posted the release annoucement on AO a couple of months ago...but, the question that occurred to me was : "What will you do with it?"
It's a development tool, nothing more. Not a browser, since the online hardware for the PS2 isn't even out yet (mind you, the Linux kit was released in May).
I am almost certain that the Linux kit is a dev tool for the inception of the codenamed "Cell" processor that will power the PS3.
