I have finally converted over into the Mac world and bought my first Macbook a few days ago and I haven't been in love with a device like this in a very long time! Absolutely love it. While browsing around on the forums about which models to get and what will be better for the future and longevity of owning a Macbook and I am starting to have doubts about the mode that I have. I have the rMBP with 8GB RAM and 256 flash storage. I am not a heavy user and mostly use my computer for regular browsing sites and may down the line get into a little video editing since I am trying to start my own Youtube channel. Seeing that I have never had a Mac before, I am just trying to see if what I have will last for some years with the usage that I have or after a year or two I will be needing the 16GB of RAM? I am not concerned with the 256 storage since I doubt I will even get anywhere close to filling that up. Not to beat a dead horse about what model is best for me since those posts are all over the place but I just want to ensure that the model that I have will last for some time before I will have to update it. Thanks in advance!
