Hi to all! I come here to get a bit of an advice (see title thread), but before that, I will start with some background about me...I think this is useful for what follows. I have been a geek for about 15 years (I am 36 now), a huge apple fan since at least 2007 (before that, I tried a lot of different computers, including tablet PCs) I have had all iphones since 2007, many different ipads, and I now also own an Apple Watch…So, one can say I am an apple fanboy ;-) I have always loved thin and light laptops, that why, when I hesitated between a 13” MBP retina and a MBA, I chose the MBA. Then, when the 12” Macbook was introduced this year, I hesitated a little bit, but decided to try it rather quickly (also because my MBA only had 4 Gb RAM, which I found limitating). I was amazed by the thinness…but I soon also found that it was a bit slow. And despite the 8 Gb RAM, using a VM with Parallels was…complicated to say the least. Finally, when used outside under the sun, the MB would slow to a crawl, telling me that I should close some apps to prevent the temperature from rising. I was getting a bit dissatisfied…then I read a bit more about Windows 10, and decided to try the hybrid Lenovo Yoga 3 Pro. It was a great machine, but agonizingly slow. Then I tried a Dell XPS 13 with a QHD touchscreen (one thing that lured me back to windows was indeed the possibility of having a touchscreen). It had a gorgeous screen and was rather quick…but I found that battery life was lackluster as soon as you would run a few programs in the background, as well as Chrome, Evernote…. Hence, I am back to square one ! Given that I loved Cortana, my idea is now to run a Win 10 VM via Parallels 11. I am thus considering buying a 13” rMBP, but I am hesitating between the different configurations. At first, I thought I would take the 8GB/256G SSD but then I thought a little bit, and wondered whether 8G would be enough, if I intend to run Win 10 in Parallels, as well as having Chrome, Excel, Evernote, Airmail 2 open and Hazel, Alfred, Onedrive, Dropbox, text expander in the background... I also do a bit of R programming from time to time. My only gaming habits consist in playing CCGs such as Hearthstone, Solforge... Finally, with regard to the size of the SSD: I usually can manage with 256 (I have 14 GO left right now, but I have to clean regularly, and sometimes I am a bit tight…notably when I have to edit some GoPro videos…but it does not happen very often) One thing to consider as well is that I won’t keep it for 3 years…if the next generation is slimmer, thinner and lighter, I will probably buy a new one a months after it’s out. Any thoughts/advices? Thanks for your help!
