Are you kidding me?

External Blu-Ray drives will cost twice as much as an Internal Blu-Ray drive. So unless you want to fork out £1000 for a drive that will be sluggish and obsolete in 3-4 years time, I'd suggest you keep your money and wait for the price tag for Blu-Ray drives and media to drop.

But then again, if you've got money to burn then go for it.
