I'm a bit late to the post...but some opinions:
Too bad they're not backed up by fact.
1)Firewire...does any consumer still use that? Seriously. Maybe folks with video cameras but FW, in my opinion and industry experts have stated that FW lost to USB over a decade ago.
Hm... So your contention is that FireWire lost out to USB back in 2000 or in 199x? The USB 2.0 standard, which supports up to 480Mbps raw data rates, was only finished in April 2000. At that point, Firewire had already been capable of those speeds for 5 years. (Yes, technically FW 400 was only capable of 400Mbps raw rates, but considering the differences in protocol overhead, FW can actually transmit between 150% and 200% more *actual* data over their respective connections.)
2)I frankly don't care about watching movies on my computers but I hear a lot of people here as well as other boards state they love watching movies on their 17-24" monitors. I do agree, now, with a lot of people demanding Blurary...it's been selling like mad (units and movies) since mid 2008...and I'd love to have a BD burner simply to backup 25-50GB on a single disc. My Sony home BD player cost $125 to my door. I own about 35 movies...all of which I paid $11.99-$17.99...all are blockbusters and all are stunning to watch on hi-def compared to their dvd counterparts. I think it would be worthwhile for Apple to include BD as an option...especially since Apple updates the Macs every 12-18 months. Do the people who want BD want to wait for the 2012 version of the Mac?...no. They may be able to go out and purchase a drive for $150-$200 but that's a pretty penny...and not sure if the consumer would then need to purchase software.
Sadly, the vast majority of movies are still not available on Blu-Ray, and won't be any time soon. Most new releases do come out on BD, but that massive back catalog of almost everything released up to a year after the PS3's release? Still DVD-only. (Except for a few that were actually released on VHS as well!
3)USB 3.0 is gonna rock...theory is 10x faster but likely 5x faster will be the norm. Heck, I'll take 3x faster. Backing up 200GB is not quick on USB 2.0.
According to the advertised USB 2.0 speeds, copying 200GB of data over the connection should take slightly an hour. I've never hit anything close to that in actual practice. (It took over an hour for 80GB in one instance.) The same data transfer between the same drives took significantly less time over both PATA and FireWire 400. In fact, the PATA and FireWire tests combined only took a few minutes longer than the USB 2.0 test did.
USB became more common because the control chips are 'dumber', and therefore less expensive. USB 3.0 will be competitive with Firewire 1600 in theory, but will actually only be competitive in practice with FireWire 800 (which was released in 2000).
For the record, I'm a fan of Blu-Ray and would love to see Blu-Ray drives sold in Macs. Unfortunately, I'm also a tech geek, so I understand why Apple hasn't gone with it yet.
