According to a Bloomberg report, Sony is thinking about making a tablet to go up against Apple's iPad, but wants more proof that consumers would buy such a device.

"We have been taking a deep look at developing a tablet for a number of years, not just because of Apple but because it creates some interesting opportunities," Mike Abary, senior vice president of Sony's Information Technology Products units, said in an interview with Bloomberg.

Abary said his company needs to see more proof of consumer demand before forging ahead, though he didn't say what it would take to convince Sony to make the leap. In just over a month since its release, Apple has sold over 1 million iPads, and with the recent international launch, we wouldn't be surprised if that number doubled before long.

"The iPad has created a new opportunity," Abary said. "Now we can get a good judgment as to whether the market is truly accepting of it. [Sony is] not convinced there is a large enough market to justify bringing out a tablet."

Increasing its lead in the tablet market before the competition has yet to even release a competing model, Apple sold about 300,000 iPad 3Gs over the weekend, a number which includes 52 days of preorder sales, says Piper Jaffray analyst Gene Munster.

That puts the 3G model on par with what the Wi-Fi only model sold during its first day of availability, which included 22 days of preorders. By Sunday afternoon, Munster reports that most of the Apple stores surveyed were sold out of the 3G model, an impressive feat when you consider the pricing premium placed on 3G models compared to their Wi-Fi counterparts.

"As of 3:00PM ET on Sunday afternoon (5/2), 49 of 50 Apple stores we called were completely sold out of the iPad 3G (most were also sold out of Wi-Fi only models," Munster wrote in a Sunday note to clients. "While it is difficult to gauge, we believe this is due to both stronger than expected demand and lower than intended supply on the part of Apple. Near-term, this may put downward pressure on luanch day/weekend statistics, but long-term we see it as positive, as consumers are definitely interested in the iPad as a new category."

Combined with the more 600,000 Wi-Fi models sold at last count, Apple likely has sold over a million iPads in all.
