Hi Shel, I'll take a first shot - > Good, reliable, fast machines to buy, preferably from > socially/environmentally responsible companies and under $1000 Lenovo Thinkpad laptops score up with Mac here: http://www.ethicalconsumer.org/buyersguides/computing/laptopsandnetbooks.aspx Lenovo's my favorite PC maker to recommend right now, with ASUS second (just below Lenovo). To get fast, get fast hardware. Here's a nice one that's on sale with NewEgg (one of the best PC sellers IMHO) for 9 more hours. https://www.newegg.com/Product/Product.aspx?Item=N82E16834860846&cm_sp=Homepage_FDD-_-P1_34-860-846-_-02262018 Very good specs for the price. Not a lot of laptops have a DVD these days so this is a plus. > Anything I should be wary of in switching operating systems In Mac, there's one or two ways of doing something. On PC, there's 15 ways of doing something - it can get confusing. Also Windows I would say is slightly less stable than Mac. Plus since Win 10 Microsoft likes to arbitrarily install updates when you're not looking which means losing your work if it's not saved/backed up/on the cloud. SO annoying! There are ways of preventing that but I haven't kept up with them. > A cheat-sheet on keyboard commands for things like taking screenshots > and making PDFs (both VERY easy to do on Mac) https://www.cio.com/article/3125513/windows/killer-keyboard-shortcuts-to-help-you-master-windows.html > What does that right button actually do?

I strongly recommend ditching Macafee or Norton and install Avast, it's free for the basic version but has a paid version that does a bunch more. I've had to salvage a bunch of PC's with either McAfee or Norton installed but never had a problem with Avast and it's at least as good. > Is there easy built-in software or freeware for making videos?
