RIM chief executive Jim Balsillie has attacked Steve Jobs over comments made on an earnings call on Monday in which the Apple chief dismissed BlackBerry as a serious challenger in the smartphone market.
Jobs said that 7in tablet devices fail to meet customer needs, but Balsillie argued that the smaller form factor fulfils a need in the market and that the use of Flash will also be crucial.
"For those of us who live outside Apple's distortion field, we know that 7in tablets will actually be a big portion of the market, and we know that Adobe Flash support actually matters to customers who want a real web experience," he said.
"We also know that, while Apple's attempt to control the ecosystem and maintain a closed platform may be good for Apple, developers want more options and customers want to fully access the overwhelming majority of web sites that use Flash."
RIM's upcoming PlayBook tablet has a 7in screen and will run Flash.
Balsillie was equally contemptuous of Jobs' claims about tablet sales, arguing that RIM's shipments continue to be strong and that the figures are not comparable because they relate to different sales periods.
"RIM has achieved record shipments for five consecutive quarters and recently shared guidance of 13.8 to 14.4 million BlackBerry smartphones for the current quarter," he said.
"Apple's preference to compare its September-ending quarter with RIM's August-ending quarter does not tell the whole story because it doesn't take into account that industry demand in September is typically stronger than the summer months."
Balsillie also queried previous Apple figures, asking why the company shipped only 8.4 million devices in its prior quarter, and whether Apple's Q4 results were padded out owing to unfulfilled Q3 customer demand and channel orders.
The RIM chief ended by highlighting other problems Apple has faced over its products, and said that it is only a matter of time before these issues affect Apple's popularity.
"As usual, whether the subject is antennas, Flash or shipments, there is more to the story, and sooner or later even people inside the distortion field will begin to resent being told half a story," he said.
