I doubt a blu ray drive with a dvd burner would be more than $10 over the price of the current dvd burner alone. If they're including in $500 i5 laptops already, (with that being the retail price), they can't cost more than $50 for the manufacterer. And I'm sure the current dvd burner drive costs close to as much.
trolling is fun isn't it. you made the ridiculous claim that bluray speeds don't compare to streaming hd, when even the slowest 1x drives (much less the 4x and 8x drives that everyone is manufacturing) have the twice the data transfer rate of 1080p content, making your point completely ridiculous. The 4x drive you laugh at is still 8 times the bandwidth/data transfer rate of streaming hd. But I guess your main intention was not to make a point but rather to troll. So go ahead, troll away.
I haven't payed anything over $15 for a bluray movie in 18+ months. In fact, over holiday season, I picked up about 20 blu rays recently released from gohastings (they were having a sale) for $4-6 each! So I think if you plan on spending $30 for blu rays, you just need to shop at better stores.
900p is still a HUGE jump up over 480p (dvd movies) and will look far better.
And how are planning to rip your brds without a blu ray drive in the MBP anyways if it doesn't have a blu ray drive? If your plan is to install a blu ray drive on your desktop, rip them on that, copy them to a hdd, and then over to your MBP, (having to clear out 25gbs of hdd space on your MBP every time you do), that sounds like a giant pain in the butt.
I would just rather be able to throw a disc or two into my laptop bag when traveling rather than have to put all that effort. Blu Ray drives are scratch proof thanks to a special coating they use on every disc. I regularly throw naked discs into my laptop bag without having had a single one scratch up ever, where as if you tried that with a dvd, it'll become unreadable in no time.
