Actually, its not BS at all. Apple is consistently behind on upgrading their chipsets, their MOBOs, and ESPECIALLY their graphics cards.
Apple excels at using the latest in what the user directly experiences, and pushing their software to get the most out what the user doesnt directly experience. It is a fallacy that apple uses the latest technology though. Think about how long it took them to upgrade to i5/i7. Especially in their desktop models. Their laptop models might/are a different story because they realease updates so much more often than the desktop lines. But because apple doesnt tend to support the new chipsets until they release the new model, it means upgrading apples is a pain in the ass.
Who cares about BluRay? Well, depsite what you think, a lot of people still deal directly with discs. Apple has chosen not to support BluRay for whatever reason. It took apple a LONG time to accept that HDMI was something they had to support. The reality is when you buy apple (and i do, i have both apple and PC), you are buying into their vision of the future. They havent always been right. They were when it came to smartphones and tablets, they were wrong when it came to other things. When they are wrong it takes them a long time to admit it.
Also their hard drives are almost always substandard.
Yes Apple has slower upgrade cycles for some products (yearly), but when the new models are released they do use the latest chipsets. Why Apple does that? Profit plain and simple. I agree that the Mac Pro is very out of date, but then again so is the whole Xeon platform that it is based on, when compared to consumer chipsets.
Substandard hard drives, what are you talking about? My iMac has a WB Black drive, so how is that substandard? In the notebook space they are a little slow (why 5400rmp?), so I wont argue there. Then again they were one of the first brands to push SSD's in a retail notebook.
If you haven't noticed Apple is removing optical drives from all new Macs, so there is no chance of Blue-ray ever coming. In any case Blue-ray as a platform is DOA, like any new optical disk media coming out in this digital age (unless you are over 40). Don't get me wrong, I still use optical media for some clients, but I might burn 2-3 DVD's a year compared to 10+ a few years ago. More clients seem to want data on a USB drive these days, basically negating the need for optical media.
Anyway, lets back on topic (I'll do that now). As for SSD vs hard drive, for editing. I don't think it makes a huge difference in the speed of the editing process itself, but it makes accessing files much faster. SSD's perform best when put into a RAID array, where they will max out SATA3's throughput.
