As nice and tempting as it all sounds and being an owner of every version of Sony's past system-based lineup (original models of PSX, PS2, PS3 and PSP, including all slimmed down versions of them as well) I must say this is a little disappointing to hear about.
All of their other products in the past that were 'slimmed' down, were really upgraded in some way shape or form (PSone got a nicer GUI, better smoothing on games and a few other minor tweaks. The PS2 slim got better smoothing too, plus built-in ethernet jack, more reliable drives, etc. and the PSP-2000 and 3000 got double the onboard RAM, Video output, built in mic, etc.) The slim PS3 seems to be going in the opposite direction to save on costs.
I have no interest in it if they remove things that I have grown to like (OtherOS support). Sure the slim PS2 lost it's initial ability to have a HDD when it was made but by the time it was released people were really pumped for the PS3 so it didn't matter as much anyway. Besides, there really wasn't many games that supported it so it really wasn't needed, hell even now there are really no games using it.
They should at least add one or two simple new things to make it more appealing because to be honest I got all of the slim versions of previous systems because they had at least one key thing they gained, this doesn't seem to be the case with this one, so yeah it's really actually quite disappointing because I was really hopeful of getting a smaller model when they were released as I pretty much knew it would happen someday based on their previous track record but this really just makes it not worth it.
It also hurts more because the economy sucks really bad right now and the PS3 is the most expensive console on the market right now still and unless they dramatically drop the price with this one, it makes it even tougher to cough up the cash for it. The older models had the benefit of being MUCH cheaper and because the economy was far better, it was easier to be able to obtain them, it isn't the case anymore.
I guess for new people who have never owned a PS3 before, they wouldn't miss having OtherOS but for the rest of us who 'may' have thought of upgrading, it kind of ruins the additional amount of possible revenue they could have gained from current owners simply upgrading too.
If they keep cutting the price and removing stuff out of it to save money I find it extremely difficult to believe that this system will really last it's 10-year lifespan they claim it to have.
Poor move Sony, poor move indeed as far as i'm concerned.
