So who's getting the 13" and 15" and why? I'm seriously debating whether or not to wait for igzo and broadwell...
My late-2008 15" just died after 5 years of faithful service. Over time it became my just-about-everything platform, including development. So I was holding my breath waiting for today, hoping... and then came the tough decisions.
- could I get by with only 13"? - Probably. I can scale to 1440x900, same as before... less physical real estate, but at higher effective resolution. Adjusting to more use of full-screen mode and a set of one-app Spaces should also help.
- 128GB, 256GB, 512GB? - 128 is out of the question. I've been pretty comfortable with 512 for quite a while, but have recently been moving more and more things to, uh, "internal cloud" storage as is. If I kill off Boot Camp, change work flow a bit, make more use of thumb drives... 256 might be just fine.
- 8GB or 16GB? - Well hell, this was the very reason I cut the 13" right out of consideration last year: no 16GB, no way. But wait... I've been reasonably okay with 8GB, and Mavericks is making some efficiency promises here, and the whole point of "no 16GB, no way" had more to do with "future-proofing" than with dire immediate need.
So huh. My ideal MBP doesn't really exist (matte screen, user serviceable), and next-gen long-term replacement for how I've *been* doing things is going to exceed $3500 (figuring in 1TB storage, tax, and at that level of expense, AppleCare for damn sure). So I thought about things, how reliant I've been on an everything platform, how I've gotten by on this iPad for so much over the past week, how many resources are just a wifi hop away, and what I really want for a development environment.
And then I ordered the new standard config 13" 8/256.
It'll do everything the previous could - except way way faster, with a couple of trade-offs - and leave nearly $2000 on the table for a primary dev one. It'll be in my hands sooner, and if it's not working out, there's the better part of 14 days to figure that and change my mind if so.
Your base considerations are clearly different than mine, but there you go... my "why".
