Probably the Most Important Thing!!!
Guys,
You've made many valid and important points on which media types are supported by the various versions of the PS3. And some of the user upgrades possible with the console (a Hard Drive upgrade is easily accomplished by anyone with minimal experience with computers, will not void the warranty and is detailed in the PS3 manual).
But beyond that, the best thing that Sony does with the PS3 is they regularly update the software and/or firmware (almost monthly it seems). Often adding new features or improving existing ones. This is a huge benefit to someone looking for a seemingly "future proof" universal type player that meets the needs of most (97%?) consumers.
As was pointed out in earlier posts, unless you need SACD and DVD A support, the PS3 looks like a "no-brainer". Especially in these tough economic times. Now let's see, $2000 for a Denon DBP-4010UDCI or $299 for a PS3?
Which other $299 Blu-ray player supports WiFi and Gigabit Ethernet? Not that $2000 Denon! That's only the beginning. The PS3 was so far ahead of it's time (and the croud) it blazed the trail and made everyone else look bad doing it.
