Blackberry has posted a video of a side-by-side comparison of their upcoming Playbook tablet with the almighty (albeit flashless) iPad. Aspects that are highlighted include browser rendering speed, flash support and HTML 5 performance. From the demo video, it’s pretty evident that the Playbook out performs the iPad in all the aforementioned tests. That said though, let’s not forget that Blackberry’s 7″ tablet won’t be released until the spring of 2011 and the iPad is already 7 months old. By the time the Playbook does hit the market, the second gen iPad should be right around the corner as well. Video after the gap.
