There aren't many, but I guess if you had to list them:
1) Slight risk of bricking your phone, but this really only applies if you're not careful, IMHO.
2) Technically it voids your warranty, however, you can always unroot, assuming your phone is still operational.
3) You won't receive OTA updates, however HTC has made a habit of not releasing timely OTA updates for their phones, and you can again unroot if you really want to.
