Well, yes and no. YMMV.
1) Bring back the 17" Macbook Pro. Yes it's big and bulky but I'm willing to put up with that for the extra screen real estate.
Not for me, thanks.
2) Bring back user upgradable memory. If it truly is a Macbook Pro then it should come with 8GB minimum and I should be able to plug in up to 32GB (or maybe even 64) as and when I need it. If the laptop was aimed at home users I could maybe see not wanting them to be able to do this but I'm a professional and I know how to open laptops and upgrade them. I should be able to do this on my own and without a trip to the Genius lab.
Well, having run the numbers on other products, I know that every connector is a reliability liability. If the memory is soldered in and factory tested, the machine will be more reliable for you, and have fewer warranty issues for Apple. I'm with Apple on this one.
3) Ports - lots of them. Wireless is nice but sometimes I prefer a hardwired network connection. Gimme a network port. I also need a couple of HDMI ports and at least 3 USB ports. Why not throw in a Firewire port too? I know that it's kind of old technology now but a lot of people still have firewire drives and would like to be able to plug them in.
Truth.
4) Bootcamp. Why not have the option to have Bootcamp pre-installed if you know you're going to use it? Or maybe a prebuilt virtualized Windows. Yes, some of use would prefer to do it ourselves but others might appreciate the convenience.
You have a good idea here, although for my use I want a Linux VM.
5) I'm tired of the race to the thinnest laptop. I want something with a battery big enough to last the whole day, or more, doing intensive processing. If that adds a half pound or a half inch so be it. This is supposed to be a big boy laptop, not some hipster toy.
Truth
6) 4K display. Could you imagine a 4K display on a sweet 17" laptop with a matte finish? Heaven.
I can imagine it, but I probably wouldn't be able to see the fine detail because my vision just isn't that good any more. But I *do* want the ability to drive a 4K external monitor the size of a football pitch right out of the box, using some kind of modern video subsystem.
