1 & 2,
I don't get all the great comments about it being lighter and smaller? It's a damn desktop. You are not meant to be carrying around in your bag like a laptop. People are suddenly going to start taking a desktop on visiting clients? Packing all the external drives away and taken the as well. That'll look really professional, asking a client to wait 30 minutes while you plug everything. Horsehocky.
3,
Looks better? It's a workstation computer, not a Ferrari. Looks only matter to the sad lot that wont use it to make money.
4, After 4 years to work on this they give a mediocre increase in raw processing power. The GPU's are great but unless you run stuff that is optimised for them they are nothing more than heaters. We should have been seeing motherboards with 4 slots in these machines not a reduction down to 1.
5, Good expandability? HA HA. If you want to double the spend on the initial machine to get a similar set up to what you can already get inside the current systems. As for CopperCripple, don't believe the carp that is said. It was a joke on release, going from optic to copper.
6, Again it's a damn desktop, doesn't need to be carried around. The only time you need to move it is when you take it out of the box and plonk it on the desk.
Or is everyone going to get a plinth and bow down to it every morning?
I will definitely get on my knees and give thanks every morning once I get one. After a couple of years using a MacBook Pro i7 after selling my 8 Core Mac Pro, I can't wait to get back to a real computer.
