Again so many tl;dr responses, so excuse me if I cover already trod ground here:
Let me start by saying that I agree that it is the higher-end, nicest piece of software out there. It has so much potential to be THE next generation machine to beat.
Now with that said, since I own all three consoles, and many older ones, and have been participating in hardware wars since the late 70's/early 80's, I can fairly say that if Sony doesn't get their ass in gear and start taking their PS3 line seriously, it's the new Betamax of gaming consoles.
I don't say that lightly, because I really, really, really want to love my PS3 as much as I loved my PS2. So I'll go over my niggles with it.
= Blu-ray is nice. Really, really nice. However, physical media is slowly slipping to the growing number of digital streaming services out there. For example, Netflix quadrupled it's streaming user base, but DVD/Blu-ray renting/buying is taking a huge hit. Blu-ray distribution was only up by 2%, and blu-ray sales only increased by 1.8%. That's awfully slow for the speed in which technology advances. Like the Betamax, it is the superior product over both DVD and streaming video. It's the same slow growth and price that hurt the Betamax that's happening right there with the Blu-ray.
= HD from Blu-ray is nice. But mostly everyone I know doesn't have an HD TV, so the thought of Blu-ray is distant in their minds. Until someone gets more HD TV hardware out there for a vastly cheaper cost, it's going to stay in that distant spot.
= Sony never, ever, ever meets their dates. All my awaited patches, releases and improvements are always put off a week to six months. I mean, I waited for Home, and it took 8 months longer than they promised. And then when I got into Home, it's basically a beta. Same with their patches for everything. Sony either needs to give us a good date, or not allow their PR machine to give us false hope. That more than anything pisses me off.
= Sony's Customer Service also sucks balls. Me and my 18 friends with PS3s play together as much as possible. We've all had some account/machine problems. Everytime we've called Sony or written Sony, they go through this series of events: 1) Tell us that it's our fault, 2) tell us that they don't have an answer, they'll get back to us (and they never do) then 3) finally admit they will take a look at our problem. I shouldn't have to go through 11 weeks of waiting before Sony tells me to send in my PS3 for a faulty Blu-ray component covered by my warranty. That pisses not just me, but all of my friends who have PS3s off. When my XBox 360 got the RRoD, my 360 was back in two weeks. And the customer service people were helpful.
= More games. I know that's partially the developers' fault, but when I read Kaz telling everyone in a interview that they intentionally made the dev kit and the PS3 architecture difficult to work with, I want to smack whoever thought that was a good idea. Honestly, more games is good, since typically 1 out of every 5 games for every system is a gem. If Sony's only releasing 10 games, that means only 2 of them were worth my time. MGS4 and LBP were the only games I thought were worth more than a rating of 8 last year.
Honestly, if Sony doesn't get their butts into gear and start making things easier for everyone all around, the PS3 is going to end up like their Betamax product. Sure, it's a better product, but when it's more pricey than the competition, and the media takes additional steps to get to production, then it's going to eventually fail to a system of lesser - but acceptable - quality.
That's just my opinion. Otherwise, you did cover some good points there.
