If it has games you would like to play, such as the exclusives, then go get one. Otherwise, don't. While some of the "ports" seem to not hold up to the games available on other consoles, they aren't that terrible. Some have enhancements but also have some performance issues, but in a sense, that balances it out. The system does have bugs, most which seem to revolve around Miiverse, but people have been able to temporarily remedy that by not having their console connected online, so if you don't mind not going online with it, you've got that option until they fix the issue.
I have one, and am enjoying it very much.
