Nobody can exactly tell why Apple names its latest tabet as "The New iPad" but not "iPad 3" like usual. However according to Slashgear, the company still making hard to gain the control of iPad3.com domain - it’s clear that Apple recognizes that some people still call it the third iPad to differentiate it from the others.
Global Access in Isle of Man is the company that has had the iPad3.com domain since January 2010, and has been known to squat on domains with the goal of later selling them. Previous disputes involving trademarked domain names that Global Access registered ended in losses to companies like Allstate, AOL and MasterCard. Since Apple obviously owns the trademark rights to the iPad name, this dispute should settle similarly to others against Global Access.
Nobody knows exactly what Apple wants to do with the domain, but it’s reasonable to expect it to be directed to the iPad page on the official Apple website. The company has been previously successful in acquiring domains like iphone5.com and iphone4s.com, both of which direct to Apple’s site.
