EDIT: My bad, I see you knew about the PS3 updates, so I got ya all wrong. Ignore my post.

 

What are your principles or do you even have any. My PS3 has been off every sense Sony pulled this move. I paid 599 for my PS3, and now they want to remove a feature i paid for. Without a rebate, apology or anything that understand how the consumer feels. Instead we get you don't use it anyway or it's not important. It was important enough for you to charge me for it. So I'm currently waiting for that one guy to make a Custom Firmware. If he can't odds are I'm going to sale my PS3, and buy a 360 maybe.

If it's your only system, and you don't care about certain things then do it. If you have another system that you can use then just wait.

I have a Wii that I play more the my PS3 anyway. The only reason I bought it was to play some 3rd party games and anime imports.

 

the CFW thing is basically "dead" in the PSP world; chances are slim that it will ever happen for PS3

Geohot basically probably is just showing a proof of concept, that its possible, but meh doubt he can be really bothered with it
