I currently own a 15" rMBP which I use for graduate school and some light gaming (sims 4 yaaaas) While I only live 3 minutes of walking distance away from my uni and carrying my rmbp with me is not a problem, it's really inconvenient for using during lectures. Until now I've been using a first gen iPad mini for lectures. I've seen people with 11" mbas in lectures but while OS X > iOS for work I prefer reading class related ebooks on a touch screen. I'm also not sure what to think of the use of actual notebooks during a lecture.. In addition, I use notability to record lectures while making some quick notes. Only problem with the ipad mini is the very obvious lag and the on screen keyboard being too small to use for proper typing. Now I've owned an iPad 2nd gen during undergrad school before and I've actually typed out 3k word reports on it without problems (though I do remember switching between pdfs and pages being a bit of a hassle). It even replaced my dying asus laptop during my last year of undergrad . However, the ultra portability of the new 12" macbook packing a whole OS X is appealing as well.. But then again, aren't 2 notebooks overkill? Are there any multi window workarounds for the ipad air 2 and how are people feeling about using an ipad air 2 with physical keyboard for work on the go? Thank you for reading!
