I have put
CFW on my friends slims,
I have a phat but I don't know which I prefer.
The slim just feels too cheaply made to me.
The phat is more hardware mod-able.
I am going to stick to my phat since I don't see any problems, when a
psp comes out with dual joysticks then I will buy it.
I really think instead of going with a slimmer version they should have just used the extra space inside the phat to do some major hardware upgrades.
