Hello, First of all, I would like to say hello to the users of the forum, as I am a new one Since one month I am thinking about getting rid of my 6 years old Samsung's Ultrabook (Series 5) and replacing it with MacBook Pro. I am a Windows user since 18 years. I've never used Mac OS, aside from iOS, until a half a year ago, when I had to use MacBook Air for job-related topics. And to be honest, I've fell in love with this OS. Such a different experience when using it on a daily-basis. I would like to get one Apple's notebook for myself. The thing is: I have no idea how Mac OS behaves on a day-to-day usage in terms of performance and reliability when it comes to having it for many years (like I've mentioned I own 6 years old Samsung which is still good to go after swapping out HDD for SDD, of course only for some basic stuff like web surfing, MS Office, super light or old games). I've read a TONS of topics and articles regarding the latest line of MacBooks Pro, but still not sure what to choose. I am used to portable notebooks, my current laptop is 13.3", Toshiba at workplace is also 13.3" (although with two external displays), MacBook Air which I am using at work, also 13.3" I really love the look and feel of MBP 13" 2017, it looks so light, minimalistic and elegant. But of course, there are cons (at least in my opinion) - dual-core and no dGPU present. I am no heavy gamer if it comes to PCs, I own a lot of consoles and preffer them over PCs. But, I also like to play some old games on my laptop (which handles them with crappy Intel HD4000 with ease). Also currently I am not doing any video editing/rendering 3D stuff. But what will bring the future? I have no idea. I saw videos that Iris Plus 650 is able to handle CS:GO or Overwatch with some medium setting, so it's more than enough for me. But what about other stuff? Real world performance difference between iGPU/dGPU? I have no clue about it. Another thing is when it comes to CPU. Currently I also own very old i5 1.6Ghz 3317U. It handles basic tasks very well, no hiccups. What it will be if it comes to real performance on Mac OS? I mean i5 which is dual core vs i7 which is quad core (a lot more futureproof, what I also have in mind). I don't want to waste a huge amount of money on the things that will be obsolete in 2 years from now on. Differences between i7 2.9 and 3.1? Is there any REAL difference or is this only a technical sheet-related difference?(and money of course) The most important thing for me is portability, when I've bought my 13.3" Samsung I loved it's compact size and weight. It is really comfortable to use on the lap, in bed, in a car. BUT if I want to have quad core and dGPU (if it's essential for futureproofing) then I am afraid that those "portability" days will be gone. I mean, I saw both MBPs in stores, I've checked them many, many times, weighted them, compared side by side. But on the other hand I've red, that when you take your MBP15 to your place, or anywhere else from the store, the feeling changes drastically I am not saying that MBP15 is heavy, but the size is what bothers me. If I would have a chance to spec up the 13" model with dGPU and quad core, I would not waste time on thinking, until now 13" was my ideal size, but with those cons (I am not sure if they are really cons as Ive never used Mac OS long enough, don't know how it behaves in the long run) it is really hard for me to choose. So what do you guys think? Anyone came from 13" to 15" and feels great with it? I would love to have the same feeling, but I am not confident enough. MBP15 is powerhouse, no doubt about it, futureproof and I can think about being creative more and more in the future, because hardware will not limit me, but the size scares me a little. As for the things I am doing on my current laptop: - Daily basic tasks, browsing, mail, youtube, spotify, netflix, all that media stuff which is common for everyone - Different OS virtualization (currently on VirtualBox for Windows), two or three OS in the same time on VM - Recording/editing audio - Once per half a year playing some old stuff games/using emulators of old systems (PSX/SNES/PSP) What I have in plan is to start developing code (no idea which exactly) so I would consider this also in futureproofing the Mac, but I guess even base MBP13 can handle this with ease. Video editing? Maybe once a year when I come back from holidays No professional stuff in that case. If you have any suggestions (I plan to max out either of them) regarding on where I could same some $$$, I will appreciate it Thanks in advance for the replies !
