Steve certainly eluded to this in the article and it is worth highlighting that the numbers game, be it megahertz or megapixels, is often a marketing attempt by a possibly inferior product to bring on the mega-hurt to their competitors by tossing up a smokescreen around their weaknesses.
Let me preface it that I'm one of those multiple device users, with an N97, BB9700 and an iPad 3G/WiFi.
My BB upgrade patterns often are driven by a broken trackball as often, RIM's new devices are, IMO, incremental and cosmetic. I should point out that the cosmetics can be decent as going through four generations of RIM products, there have been tangible feel and quality improvements.
In addition, my BB needs are very specific, it's there to serve a specific purpose, so my demands on it from a personal standpoint are irrelevant.
Many of the new improvements that RIM has deployed to try to recapture or win new "casual user" market share is starting to interfere with what I use it for, similar to how pushing the smartphone envelope has made phones less practical as plain phones, this direction makes me feel that RIM is diluting its own strengths to climb a perceived goal.
That brings me to my peeve on mobile phone development in the last few years. The mad race to make the top smart phone seems to be moving the function of a smart"phone" further and further away from a phone.
Perhaps users feel they don't need a mobile phone any more in the presence of new and ubiquitous messaging and social services, perhaps we never even needed it in the first place.
For me, I miss a smartphone that can just do its namesake right, be a phone first and foremost and put some smarts around the phone feature.
I'm seriously considering taking my N95 out of retirement to be my phone again.
