We don't have any plans for integrating tapatalk at the moment. Though, currently, our forum platform is under redevelopment. At some point after the upcoming update, we may consider adding this as a feature extension. Thanks for the suggestion!
Tapatalk is a generic forum app, and I do not think it would work with Tom's Hardware. I seen some websites make a customized tapatalk app specifically for their forum, which is what I think Tom's Hardware should do, since it is not your usual forum.
Tapatalk is typically compatible with vBulletin, whereas the Tom's Hardware forum software is proprietary. It would not be easily integrated, unfortunately. On the up-side, we are working on a mobile-friendly version, so keep your eyes peeled for this coming down the pike.
