I've just re-read this thread from the start.
Really feeling the love for Tapatalk and still cannot see a valid reason not to use it.

One I did noticed was the Ad's.

[Solution] Don't be tight, Pay for Tapatalk Pro and enjoy all your forums on your phone, loading quickly with instant forum notifications from all your subscriptions, without the need to zoom/pan/scan/fiddle - Ad Free!

For the security model, it has to use the model in place at the forum it's serving, hence the full support for vBulletin. It would be a pointless project if it did'nt.

The Tapatalk plugin is really easy to install. And has been once already on XBMC.

I don't mean to point out the obvious, but surely if there was any sort of security risks with Tapatalk, XDA-Developers would not be endorsing it for their 4 million+ member forums.
I understand caution, but over 18 months and XBMC being left behind (never thought I'd hear my self say that!!) and not a Tapatalk enabled site with anything bad to say about it...!!?

If it had any flaw's XDA would definitely not be supporting it and they would be the guys in the know for anything Smartphone/Forum security related.

I have 2 Blackberry's, 2 iPhones and an incredibly awesome Android phone at my place and they are now used far more for surfing the internet than the laptops/tablets/computers are these days.

At least give it more of chance than 12 hours (originally active for @ XBMC ).

I am but a loyal/humble/surfer/watcher of XBMC and thought I would add my 2 cents worth to this.
Just hope this no longer falls on deaf ears...!

Tapatalk FTW. Period.
Peace.
