Hi,
He wrote "on all other pads" - AFAIK, no other tablets but macs call themselves "pads", presumably because of trademarks. It also stands to reason, since iOS, Android and WinRT share very little in common. I have the greatest respect for the coders behind Vienna products, but an iPad app can't even be installed (AppStore and Windows Marketplace being proprietary), let alone *run* on other tablets. Unless it's built as a really, really fancy HTML5 website, but I rather doubt that. A very fancy cross-platform plug-in environment would be an awesome development, though, so if this be the case, I'd like to hear more!
Best,
Michiel
