rMB
I was able to demo one at the Portland Apple store last Sunday. Had a genius appointment form my 2011 MBP as apparently I am running out of disc space, looks like I will need to upgrade sometime before the end of the year. This is the last laptop Apple made with a disc drive and at the time I purchased it, ordered it with a 128 SSD. Considered upgrading the RAM and drive, but a store staff at a reseller felt that it may not be worth it due to upgrades in the software, but runs fine on OS 10.3.
Back to the rMB. Was very impressed with the build quality. The display was stunning, even readable to my "older" eyes. I was not sure what to expect of the keyboard, I have long skinny fingers, it felt very natural (my Pro keys are starting to get threadbare at the bases and occasionally pop off or get misaligned where I have to press them back into place). The track pad for a new Mac user might seem a little weird, I did not feel it was much different from using a standard Mac track pad with the addition of a couple of new features.
I did not notice any lag scrolling up and down, would wonder if that could also be due to demands on the wifi system in the store.
Am not by any means a power user and until last month kept having to schlepp back and forth between home and work on an every other week basis. Will now be working in the same locale as my home. Even with my 2011 MBP, I only have the power cord attached for charging, am now using an AirPrint capable printer and my iThings sync over Wifi on a Time Capsule in another room separate from the laptop.
Unfortunately, in my professional (health care) world, have to access work software via a VPN and function in Windows, so I do plan to Boot Camp a portion of whatever drive I end up with dedicated portion for work applications.
At this point considering purchasing the rMB fully tricked out (1.3, 512 GB) which with AppleCare comes in at just under $2K, interested when that comes out what the reviews will say. Alternatively a refurbed 27" iMac with Retina, which seem to have some pretty good deals on the Apple website. Know I am comparing apples to oranges, but would really like to purchase my last computer! Was wondering why AppleCare is significantly less expensive for an iMac than the laptops?
