Hi! I need honest opinion and insight from Mac guru here. I've been using a MBP 2011 (13" 2.3 GHz Corei5 ram 4Gb HDD 512G) until today. It's my first mac and has been sturdy and reliable all along. Sure it's been quite slow these past few years, which is very understandable. It still works okay. I plan to use it for as long as it has me but I think I should buy a new MAC as a backup, in case my old MBP faces a sudden death or something. At first, I'm looking unhurriedly for Macbook Air (prolly the secondhand 11" or something - my current MBP is kinda heavy) but then I found a secondhand Macbook 2016 on sale at around 1000$ (I live in an Asian country where there's no official Apple store) and the seller is someone I know so no worry abt the scam. The specs are: Macbook 12 early 2016 core M5 ram8 SSD512 (warranty already ran out, i think) I know that on paper, Macbook's spec seems paler in comparison with other models but someone told me that it manages the resources very well and they found no difference (with Air etc) during real usage. But I'm not sure if it stays true on the long run...? Please weigh in! Do you think I should invest in this one? or should I rather buy the cheapest model of Macbook Air 2017 OR splurge a bit more (approx. 250$ more) for the cheapest model of MBP 2017? I'm hoping to find a model that is sturdy and would last for several years. Mac products are generally expensive for me even though I think it's worth the price and a good investment for work. I simply can't afford a new one as often as other Apple fans. I usually use laptop for office work (keynote, pages and my MBP has Office for MAC. I guess that still works on new models?), internet surfing, movie watching. Quite the basic stuff. I don't use Photoshop/Adobe or image/video editor programs (I even rarely use iPhoto). I don't play games at all (not even Solitaire or minesweeper) - retina display or not : not a deal breaker for me. I can't even distinguish the two.. - portability is a plus - still undecided with single USB-C port. I think I could survive that (with a hub, of course) but need real users' opinion on this. Thank you so much in advance for your help!
