When it comes to updating the iPad mini 1st generation, would the Mini 3 be a good replacement at this time? Locally I've seen multiple places offering the Mini 3 at a low price. I'm wondering in your opinion if it is worth buying the 4 right now, especially when I can pick up a 3 for about $150 less. Yes I'm aware of how it works, faster chip, etc; however of course eventually the 3 will become outdated as will the 4 and so on, heck Apple already discontinued the 3 anyway. But do you think the 4 is worth paying the $150 more than the 3 to have it now and replace the Mini 1? Thank you
