I am looking to buy a new Mac MINI and I am not sure what I really need to get as far as configuration goes. All I really do is surf the net, do e-mails, compose a few letters to snail mail and play a few hands of solitaire. I doubt that I will ever want, need or desire to go beyond those uses. However I have heard that a Mac MINI is hard to upgrade so do not want to be penny wise and pound foolish and not buy the right model to begin with. If I go with the base model do I need to get the upgrade of Ram? I do not do spread sheets, any sort of presentations, don't make movies,or record songs etc. but as I said do write the occasional letter. Do I need to get Iwork? Am retired and want to spend my money the most efficient way possible.
