Welcome to Android Central! It really depends on what you want to use the phone for. If you just need to make calls, do some light web surfing, and maybe play a few simple games like Angry Birds, it should be fine. If you want to run the latest processor-intensive games or use the latest Android system versions (Incredible stopped at Gingerbread, although you can root it and get Ice Cream Sandwich, I think), then look for something more recent. To answer your question, the phone is essentially extinct.
