So I bought my iPad 2 about a year ago and love it, but now that it is almost 2 years old and 2 newer iPads have come out it got me thinking. How soon should I start saving to upgrade my iPad? I have not seen any real problems like lag or anything, but how long do you think we as iPad 2 owners have until apple stops sending updates to it, and it becomes to slow to run the most up to date apps? I really love my iPad and don't want to go get another one, but I know as some point it will happen. How soon do you guys think that will be?
