In the ever increasing furry over Apple’s upcoming tablet device, many are looking to market indicators for a hint of what’s to come. Now there are two markets that indicate “iPad” as the upcoming tablet name: betting websites and domain name registrations.

Betting website Paddy Power has changed the odds in the Apple tablet naming competition. Yesterday “iPad” had a strong lead over “iSlate” with odds 1/3 and 2/1 respectively. Last night, however, “iSlate” odds improved dramatically from 2/1 to 5/4. While the 1/3 odds for “iPad” remained the same, these changes indicate that the recent “iPad” trademarks may not be as convincing as they were earlier in the week when the news first hit.

Meanwhile, dark horse “iBook” has finally joined the race today jumping in at 4th place with 12/1 odds, just behind “iTablet” which has stayed steady at 10/1 odds since Saturday.

While betters may be growing more indecisive, domain investors and speculators are pointing to “iPad” as the tablet name. In analytics I ran earlier this morning on the number of .COM domains registered over the past 48 hours, the keyword “iPad” increased by 93 domains, “iSlate” increased by 76, “iTablet” scored 14, and “iBook” grabbed fourth place with just 12 domain registrations.
