I think I've decided that my next computer will be a Macbook and that the 256gb ssd will be fine for me, but I can't decide whether to just go with the base 1.1 processor or upgrade to the 1.3. I'd welcome any advice. I continue to be entirely happy with my current computer (a 2012 Macbook Pro 2.9ghz i7, 8gb of ram, with the older spinning style hard drive). The main thing I want in a new computer is for it to be lighter and a better screen. As long as the performance was "as good as" or "on par with" the current one but in a lighter package and better screen, I'll be very happy. I've been keeping a close eye on activity monitor over the last couple of days to get a sense of how much I'm actually using what my current computer has to offer. As I suspected, my normal usage doesn't push it very hard at all. I primarily watched the "bottom line" numbers about how much of the processor was idle. Here's a summary - Percent of processor idle: approximate time in that range 90: 35 80: 35 70: 10 60: 10 50: 5 less than 50 idle: 5 From previous input, I've gathered that the newer core-M processors would be slower than what I currently have, but perhaps not as much as the numbers alone would indicate, which is still hard to get my mind around. The newer macbook would also be an upgrade for me to a solid state drive. I think my usage is relatively light, including safari, firefox, mail, iTunes, spotify, occasional editing of a few pictures in photos, preview, word, powerpoint, and excel. The word files can get long and include some basic images. Powerpoint files also can get larger with images. I'm a student/teacher. So, my primary uses are research or writing projects, ranging from article to book length in word, and teaching, which can involve presentations with powerpoint. So, with that in mind, would you recommend a 1.1 or 1.3 processor? Both would be within budget, but I'd rather not get more than I need, especially because I'll also be purchasing a portable CD/DVD drive and a usb-c hub for it.
