Hello, After asking what would be the best choice between a 2015 M 1.3Ghz VS 2016 M3, I am wondering it this 2016 M3 would still be enough for my needs. I am about to pull the trigger for a 2016 used one : - M3 for 1000€ ($1060) - M5 for 1200€ ($1275) But I already have a powerful 2014 Macbook Pro 15" i7 for the biggest tasks. However, I would like to buy this Macbook to use it when I am not on the desk (for example, at the end of the day, to continue to work on the couch without a big machine on me) and also when I am travelling. Because of the size of my 15", it's really difficult to use it on my train or plane trips (and I move a lot). Main usages would be : - Web development with Coda 2 / Atom - Web browsing So the disk space is not a problem - I don't bother if it's only 256Gb actually. However, I still want a powerful computer - which will be usable for at least 2-3 years as a second machine. So I know that the M3 would probably be the way to go - but I have read that it sometimes lags during scroll on some pages, or when using Mission Control for example. What is your opinion? Thanks!
