1) The retina is barely thinner than the regular MBP, but sacrifices the extra space for an optional drive for minimal thinness. Seems silly to me.
3) Why on earth would I run a retina display at an effective 1440x900 when I could run it and a much more spacious 1920x1200?
4) Thunderbolt Display has a Thunderbolt port on it for other Thunderbolt stuff.
5) Look at the evidence.
6) That extra weight is made up by your precious adapters you need for your Thunderbolt ports.
Barely thinner? It's not barely thinner, it's significantly thinner. Apple officially doesn't support a second drive, if they would, they could have made a better use from the cMBP chassis... plenty of space for a better GPU+cooling, more RAM slots AND another drive slot. Or two mSATA slots.
3) Well, duh... And it does look good @1920*1200... even non-HiDPI.
4) The single most expensive display on the planet... You can get two Dells with same panel for the same money. (Which you can't connect on the uMBP, and CAN on the retina...)
5) Call me blind but it seems to me it just depends whether you prefer reflection over glow. I don't care much about it though, I didn't on the older glossy which was FAR worse.
6) not really. I don't *need* ethernet on the go, nor do I need FW800 anywhere except it my studio... So that's where the adapters remain. And I don't need an adapter for HDMI because it's the standard - so I can connect mostly to wherever I wish.
Been on the fence for a while to be honest, and I
do regret the option of *any* 2.5" drive, or two of them for that matter. That is the setup I had in my last uMBP.
I was impressed by the sound (it's quieter then my Mac Pro I used to have in the studio), RAM latency optimisation, and two TB ports available while driving an external screen via HDMI.
The retina screen, (although I do admit that it does look awesome) wasn't a deciding factor when I ordered it.
The retina as well could house a 2nd mSATA drive if they'd sacrifice one battery cell, which I wish they did.
I kinda hoped Apple would combine the ideas of rMBP as bleeding edge and cMBP into an awesome laptop. A tad thinner, retina screen optional cMBP with dual mSATA drive slots, swappable RAM, no optical drive and the same optimised thermals... That would be a great laptop. Would sell my retina in a split second if they made it.
