Hi, all. This is my first post here so bear with me. I just bought my first Mac...a used MBP. It's a 2010-2011 15.4" 2.53 ghz i5, 4gb ram running Yosemite 10.10 with a 500 gb hybrid drive. It was an apple leased unit that was refurbed by apple techs and everything is supposedly new inside. It comes with a 90 day warranty. I paid $750. First of all, did I pay way too much, ouch. Also any suggestions on what more I can do in terms of upgrading, and is it worth upgrading. Mainly, for productivity, I'm going to be writing. It comes with 2013 IWorks, so Pages, but I'm used to MS Word for Mac. Is a Pages document easy to convert to Word doc. And what freebie word compatible program do you guys recommend. I do have a copy of word for mac 2004, but I think its too old for this system. Am I correct? In any case, all answers most appreciated.
