I have a 13" rMBP that is 28 months old. I replace my computers at about the 30 month mark while it still has Applecare, and I am thinking about whether the new iPad Pros will be a reasonable replacement. Part of why I want to replace it is that I am frequently on the road without easy electrical access, and it is much more difficult to keep a computer charged than an iPad. I use a hotspot for my internet access most of the time. I have 16GB of RAM because I tend to keep a lot of things in process at once and I loathe slow response times. The only thing I can currently think of that I might miss is the full version of Excel and maybe Word. I do a lot of research, write a lot, read some, have way too much email, work with photos, do some music things, but nothing creative. I am thrilled to have a pencil option and I was waiting for the smaller one because I thought the larger iPP was too big for reading comfortably and holding for extended periods of time. I don't care for storing things in the cloud, although I do have cloud accounts, I just know the day will come when it will really suck for people who only have all their stuff there, so the 256GB makes it much more attractive. What things does one miss when trying to make iPad Pro your main computing device? Will I miss OSX too much?
