Well said, for those that "do their homework" the rMB is a very solid system and performs exactly as expected. Apple can only build on what is already on offer from the current rMB. I for one will upgrade to Skylake soon as it`s released, as being one who relies on OS X and the Mac for their livelihood it`s a basic calc.
Q-6
While I would normally pre-order or be ready to pounce as soon as orders opened up on a new Apple product that excited me, all the bleeding edge tech had me worried on this one. I wanted to see at least a few good reviews and preferably put my hands on one before ordering. But after doing those things I was reassured enough to place an order.
When I got my 1.3/512 rMB it was a bit painful to set up because of the 10.10.2 WiFi bug and USB-C but once I got my Time Machine recovery done under 10.10.3 it was smooth sailing.
I expected it to be great at routine tasks like Office apps, surfing, video playback, music, drawing, design and and other highly interactive apps that feature the user as the bottleneck. And it was!
What I did not really expect, was how good it turned out to be at more intensive tasks like photo processing, database work, development etc. I mean it's no speed demon there, but it's impreesive for 5wTDP. It was faster than my ultimate 2013/14 MBA at routine tasks and only about 15% slower at my common sustained tasks (better if I'm docked and cooling it)
I do a lot of data analysis, loading many CSV files with around 10M record's each. And do queries against multiple 100M row tables. And the rMB is surprisingly good at it. It's slower than my MBA but still quite usable. That really impresses me. What took 3 or 4 minutes on my MBA only takes 4-5 on my rMB
I did my research and what seemed suitable for my use more than met my expectations. I did a lot of testing in the first week pushing it's envelope to make sure and I am. While there are lots of things it's NOT good at, (anything taxing CPU and GPU simultaneously or keeps both CPU cores taxed for more than a minute or so it pretty much sucks at) it's great at the things I do daily, and good at the rest of the things I need to do on an ultrabook.
If you are coming to a rMB from a quad core rMBP you taxed in any way you may very well be diassapointed. Similar for a recent dual core rMBP but to less of a degree. If you are coming from a recent but not current MBA you did not tax heavily I'd suggest your chances of being happy are good. But there are exceptions.
The rMB isn't perfect, isn't good for really taxing sustained work, but it can really be a great machine for many people's routine use and is worth looking at if it apeals to you.
There, a nice positive but hopefully realistic post. I feel much better now.
