I'm retired, handicapped and have a very limited income. The wonderful MacBookPro I bought over 6 years ago before losing my job is starting to make some sounds like the hard drive might be on its way out. Before my Applecare expired, the 250GB hard drive crashed and Apple replaced it with a 500GB and a new logic board but there's no Applecare left. I have neither enough money nor credit rating to buy a new MacBook or MacBookPro. Basically all I do with the MacBookPro is surf the Internet, do quite a bit of emailing with friends, family and military buddies and look at daily newspapers and periodicals. I don't know enough about the latest iPad's capabilities. What would I lose using it exclusively, other than slow typing? Thank you very much for any assistance you can offer.
