Although, Apple hasn't disclosed an official release date for the launch of its iPad, but it is rumored that the highly anticipated tablet will hit the markets on March 26.

Both MacRumors' Arnold Kim and the Examiner have learnt from tipsters that Apple stores will initiate selling the iPad on Friday, March 26 at 6 p.m.

"The upcoming iPad launch may be somewhat limited as a manufacturing bottleneck has impacted production of Apple's newest device", Misek posted. "An unspecified production problem at the iPad's manufacturer, Hon Hai Precision, will likely limit the launch region to the U.S. and the number of units available to roughly 300K in the month of march, far lower than the company's initial estimate of 1,000K units".

Apple has revealed that the iPad without 3G will initiate shipping late March. The iPad including 3G should be shipping about 30 days later, Apple claimed.

An analyst propelled a rumor earlier this week that tight inventories might delay iPad shipments by a month, but an Apple spokeswoman told Wired.com that the iPad was on schedule to ship by late March.
