I suppose those are some distinct advantages, although it would be great to be able to swap in your own Blu Ray drive into it.
It's the idea of not using a lot of the ports that gets me thinking that it might be a waste for me. I don't use eSATA or Firewire, as I said before, and while the internal hard drive is a nice feature, it isn't essential. Might be nice for Time Machine backups though.
It looks like I would be getting a better deal because I'd be using all the features it offers rather than just half of them, especially with a pretty big price difference. Its a bit of a steep price to pay to get just one extra usb 3.0 port, a SATA port and a Blu Ray drive I might not be able to swap out should it break, and a premium I can't afford at the moment. I have a usb BR drive already which works great and is very portable for when I go see my friends at their university, and I'm only earning minimum wage at the moment, so I don't know if I could justify it unless I was going to make use of every feature it offered.
But hey, you feel like being generous and buying it for me if and when it comes out, I'll welcome it with open arms and you with a nice homemade pizza.
And yeah...where the heck is the Belkin Dock? What happened to the whole taking pre-orders thing?
