The iPad is all the rage right now, and optimism for its sales continues to rise it seems. iSuppli gave a conservative estimate of seven million iPads for the rest of 2010 and 14.4 million next year, saying more sales could happen with Flash support.

“The iPad s attractive design, compelling applications and multi-touch capability, key components of Apple Inc. s past successes, will help to offset the initial omission of Adobe Flash from the device,” said iSuppli to Paid Content {link no longer active}.

Others are being more conservative, like Piper Jaffray from Wall Street who thinks the iPad will move between three and four million in its first 12 months on the market. His firm initially predicted that only 1.9 million units would be sold.

For contrast’s sake, Apple sold over five million iPhones during the device’s first 12 months on market.
