I'm considering buying a 2008 Mac Pro off of eBay. They are affordable and seem to be upgradable. How future proof would this be? Im looking for something to last 5-7 years. Is there a better option? I am a student who recently went back college to get a degree. I have an iPad and that's what I like to take to class. I like to take handwritten notes on it. But I need to run desktop applications every now and then. I also would like to work in a home office with a big monitor when I don't feel like looking at the smaller iPad screen. I'm also a keyboard fanatic, and I prefer mechanical keyboards which is why I don't have a MacBook. I had a 2014 MacBook Pro, but hated the keyboard. I liked the keyboard from my 2007 white MacBook WAY better. My current setup is an iPad Air with the Logitech k811 keyboard which I like a lot. I tried using that keyboard paired with the MacBook Pro but the whole setup felt awkward and wasn't good for productivity. I'm looking for a variety of ideas and opinions and I would like to hear how all of you like your current products so that I can make the best decision for myself. Thanks in advance.
