Earlier this year, we looked at some of the HTML5 compatibility tests that were showing up on HTML5 Test and at the time RIM was gaining ground with BlackBerry 10 only being beaten out by Tizen. Looking at the site now though, RIM has blown past Tizen and has jumped to first place in both the mobile and tablet categories. Needless to say, it's good thing to see them working so hard on HTML5 but at the end of the day it's going to take more than HTML5 scores to make BlackBerry 10 a success.
How would you market an industry buzzword such as HTML5 to the masses? They tried that with Flash in the past with arguably mixed results. How many "normal" folks can even explain why HTML5 is great and how it will improve the platform as a whole? I can't imagine a commercial explaining HTML5 hitting the airwaves. Not trying to sound negative here, just keeping it real. The road is long and great HTML5 compatibility is only one rest stop on it.
