I have looked at both 2015 and 2016 models and I know I want the bigger screen of the 15" since I am coming from an Airport Air -13. Have been trying both in different stores and here is my take. Appreciate any insight. in AppleStore i put both at 70% brightness and 50% volume and played songs from iTunes. Made sure no other applications were running except Activity Monitor and after a few minutes both machines increased the remaining battery time until both stabilized, -16 on 7h and 30 minutes while the -15 showed 8h and 39 minutes. I have read several tests that seems to indicate the new -16 has better battery life for CPU intensive tasks. However I find most of the time that you want long battery life when reading emails, listening to songs playing videos etc. If you plan to do final cut pro editing I think most people make sure they are close to a power outlet for that. The -15 was the base model still sold in Applestore with no dGPU. The -16 was the base model as well with Radeon 450. What I like about the - 16: - lightness and smaller size - new architecture (hopefully means longer life expectancy support wise from Apple) - Better screen but note there that once I dialed down the screen intensity the -15 looked just as nice if not more bright then the -16. - Touchbar, I actually like it - From what i have rad it stays cooler and much quieter since fan runs less and this is something I really like! Negatives of the -16: - The keyboard. the one I tried in the Applestore had a semi functioning Command key left of the space bar. - keyboard again, sound wise it is quite loud and I have read so many reports about high pitch keys etc. Although to be fair the space bar on the -15 was as loud or even louder than any key on the -16 and the keyboard on the -16 feels nice to write on but not quite as good as the "classic" one. Positives of the -15: - Keyboard, the same excellent one that I have used for many years on my 2013 Air. - Ports, mostly I am happy wth SD card slot! - Battery life seems better than the -16?!! (for none CPU intensive tasks at least) - CPU/Speed etc, starting up a few apps like Garage band I noticed no difference in speed. - Sound and screen almost as good as the -16. Negatives of the -15: - old architecture, will this have more than a year of less useful life before it doesn't get supported by Apple any longer? - weight and size, it does make a difference... - No dGPU so limited ability to play games and penalty when using Final Cut Pro. I keep going back and forth and hadn't it been for the keyboard I would have ordered the -16 long time ago. But maybe it grows on you like I have read some comments etc. There is always the waiting game to play but I doubt they will change much except upgrading CPU and GPU a little bit. Pretty sure keyboard will stay the same etc. Cant really wait either since my son will need to take over my existing MBA and i want to replace with something a bit more powerful. Oh, I almost forgot but here is what I plan to use it for: - Virtual machine running Windows (7 and soon 10) - Office package for Mac - edit videos, some 4k ones. ( not long clips but maybe 5 minute ones that I will merge) - some games, Civ 4 and 6 and some WoW. - Photo editing. - Some programming as well. - I type a lot(!) so keyboard will be used for sure. - Skype, many hours a day on audio conferences! (this is where multitasking comes in ) - Seriously multitasking is something I do a lot so running a VM, using Office, editing a picture while having a bunch of other apps open as well etc. Most of the activities will actually be better on a 15" than the 13" MBA I have today so I definitely want a 15 inch MBP, only question is go for an older model or take chance on the new one??? Before anyone suggest a Windows machine, don't! I have been using Macs for 25 years and my first was the original Plus and my first real job was creating invoicing programs on Macs so skipping OS X is not an option. I have tried tons of other brands in my roles at different jobs and nothing comes close to a Mac. Thanks!
