As a hardcore phone user in regards to this forum, tapa talk is a fad that will soon be obsolete.
With phone browsers now being capable to render pages just like a regular web browser in practically pc time, specific app's to strip away all the pretty bells and whistles just aren't needed.
Almost any android phone displays eurobricks in perfect viewing form, I know, I'm on my second android phone. Knowing a few people that access the site on iphones and ipods, I get the same info, it displays fine. My brother on law has a windows phone and I did use it once too look at eurobricks and it didn't have any problems, but it was a limited test.
About 3-4 years ago when I had a blackberry, I was an advocate for these types of enhancements, but back then browsers couldn't handle all the coding behind most forums.
My point is with anything made in the last 2 years, you don't need something like tapa talk. Also in my opinion the app sucks and is not totally free. For the very limited number of people who would probably use it, it wouldn't be worth the investment.(timewise)
