Barclays Capital analyst Ben Reitzes tells clients in an note — as reported by “Barron’s” (http://macte.ch/rfRpL) — that he talked with a research analyst at Forrester Research and says the iPad is doing well in the corporate world.

His conclusions from the call are that the iPad is “running far ahead of its tablet competition and its their game to lose.” There is opportunity for others, including Google’s Android and for Research in Motion, Reitzes says. Apple hasn’t set up an enterprise salesforce, but it is “listening to enterprise customers,” he adds.

Reitzes notes that Forrester’s work supports the view more and more corporate users are “buying devices and bringing them into work.” So far, Apple is the “winner in the consumerization of IT,” he argues. Also, Forrester sees the tablet computer co-existing with both smartphone and laptop, though “it does delay laptop replacements.” Barclays is estimating 47 million tablets will be sold this year, including 33.7 million iPads.
