I'd say no. Unlike the original iPods (which are still great and in pretty high demand in certain areas), the iPads are too multifunctional to age well. It's hardware won't keep up with the software or the third-party apps, which is, for most people, the major attraction to a tablet. It's already been excluded from official iOS updates since like iOS 6.
If you get a particularly pristine unit (like, in the box, shrink-wrapped and unopened), it may have some worth to collectors in the future. May not see a very big return on your investment though.
