I've been wondering the same thing - I would only use tapatalk for NSC. At the moment, I persevere with my mobile device's interweb browser, which isn't really suited to NSC.
On the old verson of tapatalk I'd say no - it wasn't worth it but its a bit better now although mine doesn't look like the above screen shots so I've obviously not tweaked my settings or something geeky...
And particularly worth it if you're a Southampton fan. Not only can you get access to the wonderful world of NSC via Tapatalk, but you can even post (three times a day) to your own truly shithouse site.
