The only part I found a little bit annoying is he stated people "may not like a BB10 phone if it looked like a mini playbook". Like, why not? It unifies the products and reinforces the bridge feature
The playbook didn't catch-on like RIM hoped because, as the writer stated, they "had a miserable app selection when it came-out"...and it didn't have native PIM
IMO, the only reason the playbook found some success was because of the quality of the hardware, it could bridge with the phone, and it's lower price (IMO a crap-hardware lower priced tablet still wouldn't sell)
RIM has been pushing HTML5 for a while now. It's the future, but native app development is the present. And it will be a long time before HTML5 can do all the things a native app can do. Palm bet the house on HTML5 and lost.
