Sony PlayStation 3 Slim
The story here, then, is all about design, and it’s generally a good one. For starters, the Slim is 33 percent smaller and 36 percent lighter than its predecessors, and it really does look significantly more compact when you put it up against the “fat” PS3. Beauty, of course, is in the eye of the beholder, and many people, including this reviewer, think the Slim’s new frame is fairly fetching.

In that regard, the PS3 Slim’s new design and finish seem well thought out. And the new system is not without a little glam–there’s a mirrored strip on the front of the unit next to the opening of the slot-loading disc player and some glossy plastic on the sides. Those shiny finishes, like the glossy finish on the “fat” PS3, do pick up fingerprints, and it’s also worth noting that the matte finish does absorb the oil from your skin and attracts smudges. In other words, if you end up handling your PS3, expect to have to wipe it off from time to time just like the old “fat” model.

More important than some branding changes (the PS3 logo and lettering has undergone a redesign), the touch-sensitive power on/off and eject buttons on the front of the unit have been replaced by standard push buttons and the master power switch that was on the back of the old unit has been removed (you still can’t charge the controllers while the system is off).
Some people will like that the master power switch is gone, but parents with small children would probably prefer if Sony had left it on the back to keep their toddlers from accidentally turning on the system. The new button in front is nice and responsive and doesn’t require too firm a touch to turn the system either on or off (this system appears to boot up just as quickly as the old system–in just less than 20 seconds), so your little ones will have no problem firing up your PS3 in your absence.

According to Sony, to achieve the new small size, the internal design architecture of the PS3 Slim has been completely redesigned, “from the main semiconductors and power supply unit to the cooling mechanism.” As always, we’re impressed that Sony engineers have been able to build the power supply into the system itself rather than forcing you to deal with a giant external power supply like the one found on the Xbox 360.
The PS3 Slim is powered by a new 45nm version of the Cell processor, which runs at the same speed as the 60nm processor in the “old” PS3 but is smaller and more energy efficient. Company representatives said that power consumption for the Slim has been cut from 280 watts to 250 watts.

Disadvantages: Lacks backward support for PS2 games; no infrared port means non-Bluetooth universal remotes aren’t compatible; online gaming, media, and commerce options still aren’t as fully developed as Xbox Live, though they’re getting better
