I've had a 12" MacBook for about half a year and am seriously considering replacing it with a 12.9" IPP. The MacBook has been just 'ok' for me. I don't care much about the keyboard (it's pretty loud for a classroom environment, for example, and the lack of travel makes it exhausting to type on for me) and I've had persistent WiFi issues with it - doesn't seem to play well with distributed WiFi setups. My main uses: - using Google Docs and (if I can't avoid it) MS Office. I mainly do word processing, creating classroom materials with tables, lots of graphics, writing lesson plans (elaborate tables but no graphics), minimal use of Excel. Other than that, most of our school tools are in a browser, so there it doesn't matter much what I use to work. - in the classroom, I mainly need to show students stuff if I need to look up something on the Internet, I need to be able to quickly see my lesson plan, take notes etc. My thoughts so far: - in terms of productivity, I should be able to get away with it. One thing that really bugs me about the MacBook is that I have to enter the password every time I have to unlock it. I need to keep autolock enabled on it because, well, it's a classroom and there's student info, tests etc on that laptop. The fingerprint reader would be a godsend. - I'm just worried that when I go abroad (I'm a language teacher and I spend about a month per year abroad with classes), the IPP may not be enough as a primary device. At home, I have an additional 15" rMBP, so when I need to do serious work, I'll do it on that, but it's too heavy and bulky to carry on a plane. This iPad will not be used in the traditional iPad manner (media consumption etc). I have an iPad Air 2 at home and basically never use it. I've considered a Surface Pro 4, but I'm reluctant to move to Windows 10 - from experience, it's always been a buggy, unpolished experience, although I know that the SP4 would probably be the safer choice for me in terms of being able to handle everything that may pop up. So what's your honest opinion on this?
