Read an interesting review of the PS3...
Here is the summary:
The Good: * The hardware looks great, and runs nearly silently and very cool
* Wireless controller is light and feels great
* Great-looking Blu-ray movie playback
* Price is low for a Bluy-ray player
* A lot of multimedia options
* Solid backwards compatibility
The Bad: * Terrible online store
* Slow, unintuitive browser
* No background downloading
* Games continue to play even if you eject the disc; you have to manually restart the UI via the controller
* Messy UI
* HD scaler doesn't work right
* Price is high for a video game console
* No rumble, controller loses sync with system sometimes; little game support for motion-sensing features
* Uninspired launch lineup
The Ugly: * Knowing that no one is actually playing this thing, every system is waiting in a box somewhere for the eBay profit
