Hi All. I've had my MacBook for three weeks now and thought I'd share some impressions. I had been checking in at Apple stores on my travels and finally found what I wanted at the Reading store - Space Grey 1.2 512GB. So I got it! The size, weight and screen are great. I'm finding I'm actually more accurate on the keyboard than my other machines even though I would normally prefer more cushioned keys. I don't have a problem with speed - it handles having Safari, Mail, iTunes, Messages and VMWare running OS X open at once fine for me. The only thing have found is OX X freezing in VMWare since upgrading to 10.10.4. I have a feeling that may be VMWare. Battery is good, if not up to iPad standards. It still drains a few percentage even when asleep with nothing open and without powernap enabled. Hoping 10.11 will help there. The only thing I'd really like is to be able to have portrait orientation in iBooks. But what I really love about it is the sound. It has revitalised my music collection. The separation and depth is can achieve is brilliant. In iTunes I have the equaliser turned off, the Sound Enhancer set between half and three quarters, volume full in iTunes and volume about half way on the MacBook, sit it on my lap and enjoy! It has been a long time since I enjoyed my music this much. I love being able to hear the different instruments, along with clear vocals. Could the Beats acquisition have had an influence on the sound on this machine? It has even dramatically improved the sound via AppleTV to my HiFi. It is in stereo again and good separation of the instrumentation. I am also liking iTunes 12. Seems to have gone some way to making organising my collections easier and more intuitive. I used the visualiser again for the first time in a while and it was nice to see the new additions (I like that they usually add a new element to the main visualiser with every major upgrade). All in all I am very happy with this new machine. Even though it is my second machine, I find it is so good I am using it nearly every day and turning to it rather than my iPad, except for iBooks. Finally, the force touch trackpad is great! Being able to move and resize windows with one finger is so good. I think it seems so normal because the click is available anywhere on the pad. Anyway, that is what I have found after three weeks use. Hope it is of interest.
