blackbearnh writes: There's been a lot of noise recently about which mobile devices will support what development environments, and whether the iPhone's lockout of Flash hurts Apple more, or Adobe. But Jim Balsillie, co-CEO of Research in Motion (you know, the Blackberry guys...) is betting the house that HTML5 and the mobile web is really where the future lies. In an interview promoting the Web 2.0 Summit, Balsillie talks about RIM's new emphasis on the web, what the reemergence of Microsoft in the mobile market might mean, and if cell phones and tablets need to converge. "You start asking the question: If you're carrying around a tablet, how much performance do you want in the smartphone? Because you want to do a certain set of tasks really well, but you don't want the smartphone to be a proxy for a tablet-type job because now you've got the tablet. The interplay is uncertain."
