Apple on Monday said demand for the iPad 2 during its first weekend on sale was “amazing.”

[ad#Google Adsense 300×250 in story]”Demand for the next generation iPad 2 has been amazing,” Apple spokesperson Trudy Muller, told The Loop. “We are working hard to get iPad 2 into the hands of every customer who wants one as quickly as possible.”

Apple would not say exactly how many iPad 2s were sold over the weekend.

The iPad 2 went on sale at 5:00 pm local time on Friday and by the end of the weekend, there wasn’t an iPad 2 to be found anywhere in the country, according to Piper Jaffray analyst Gene Munster.

Munster and his team spoke with iPad 2 buyers in New York and Minneapolis, and called Apple Stores and other retailers on Saturday and Sunday. Munster said he believes the iPad 2 was sold out on Saturday.

Other interesting notes from Munster’s checks showed that 70 percent of iPad 2 buyers were new to the iPad. In addition, the split between Mac (51%) owners and PC (49%) owners was almost even.

Munster also found that of the people buying an iPad 2, 47 percent purchased a 3G model and 41 percent were buying the 32GB model.
