I've been tossing around which Macbook configuration to get and am hoping for some advice or opinions. I want a 13" Mac, (this screen size seems a good compromise for me for screen space and portability), but I'm unsure which processor to get, or if a pro might be better. I'm replacing an aging iMac so it will be my go to computer. I recently retired but want to start doing some programming in the future as I really enjoyed this in school many years ago but got sidetracked with another career direction. The point here is I really have no idea what types of compilers I might start using, or languages for that matter, but I want the machine to have the capability, at least on a beginners level. I'm also considering running a 24" 4k monitor at 60 Hz. I know a lot of folks might disagree with me but I'm thinking a 128 SSD will probably be enough, I currently have my photos and music in the cloud and I'm thinking I could always get a jetdrive or even thumb drive or such if needed leaving the majority of the SSD pretty much available for hard work. Honestly I currently use a chromebook and actually love it for the basic tasks, such as email and web browsing so I've learned to do without much drive space. Anyhow, right now I see BB has a 1.6 i5, 8, 128 for $849 which seems decent to me but I worry if that processor is up to the task of driving a 4k monitor. For $1149 I could upgrade to the 2.2Hz i7, but that's an extra $300, (Unfortunately I rarely see nice prices on the upgraded processors, perhaps I'm not looking in the right places?). Alternatively, the rMBP with 2.7 i5, 8, 128 isn't much more at $1179. I wonder which benchmarks better, the 2.7 i5 in the pro or the 2.2 i7 in the Air? I really don't care to spend a lot more and if I'll be running a 24" 4k the Air's lesser display won't matter as much to me. In fact last year I bought my 7 yr old a 4GB Air and I love the form and lightness, though the Pro isn't much heavier, (Capt Obvious, ha ha). Add to that the threat of new Macs coming out in a few months... --- Post Merged, Jul 11, 2016 --- Well, after a bit more research, I think I answered some of my own questions. According to the buyers guide, the 2.7 i5 in the 13" rMBP benches at 6161 on Geekbench whereas the 2.2 i7 in the Air benched at 6251 meaning that the upgraded Air actually performs better, albeit not by much and also not sure how much the iris 6100 graphics adds over the 6000, at least as far as running a 4k monitor. Huh, at first I was thinking well then, the Air it is, but jeez, for only a $30 difference one does get the retina display and force touch trackpad, (thinking the air doesn't have the upgraded trackpad?), oh and a few extra ports as well. So now, the question might be would the base model Air with the 1.6 i5 be up to the task. At $300 less that's a significant difference and almost pays for the 4k display right there.... it's considerably slower though, benching at 5094.
