If this is the best you can do with an HTML5 'app' then native apps have a long future. It's buggy, laggy, animations are wrong, graphics are low resolution in places, and user interface widgets are odd and non standard.
That's why I'd rather just have the regular old "Web" for stuff like this. There seem to be a lot of experiments to 'appize' Web sites for tablets and the like, and while most of them look better than typical Web pages at first glance, they're usually laggy and less immediate than if you'd just seen a regular web page in the first place (a common issue is scrolling.. if I get the dreaded 8 frames per second effect, I'm outta there).
but http://m.ft.com is clean, nice and fast. personally i often find the mobile version of sites nicer (in a similar way to the print view is often the best way to read a page)
edit: ugh you need to spoof your browser to access http://m.ft.com on the desktop.
Yep. After using the NY Times Chrome "app" for a while I've gone back to using the web page. I can take in more information at a glance and spend less time paging. It's profoundly ironic that progress in user interfaces in the 21st century is construed as making things look more like their real-world counterparts.
