Judging by the news that Apple has supported the iPad 2 for 2,000 days has me thinking. With ALL of the iPad Pros advantages Apple Pencil, Smart Connector and so on how long will Apple continue support for the iPad Pro line ? My estimation is about 1,000 days or 3 years ? Why ? Because Apple will eventually cut support for devices with just 2GB of RAM as the limiting factor. Also in 3 years the iPad Air 2 will be 5 years old. Also a device with 2GB of RAM. I won't go into speculation about phones because they are different animals and people do not keep them past 2 years they get dropped etc. Even though Apple supports them. Apple will however IMO keep supporting the 12.9 Pro which has 4GB of RAM but in reality if your budget can afford a 12.9 Pro with all the improvements I can imagine coming in 1 or 2 years few of these giant tablets will even be around at least the original ones.
