"It remains to be seen which of these tablet devices or other new entries will be able to successfully compete," said Paul Carton, ChangeWave's vice president of research, in a description of the survey results. "Each faces an uphill battle with the refreshed iPad 2 hitting the shelves on March 11."

ChangeWave surveyed consumers last month, before Apple CEO , which officially hits Apple's retail and online stores tomorrow.

Carton sees Apple's position as nearly unassailable because of its strength in customer satisfaction.

Of the people surveyed who owned an iPad, 70% said they were "very satisfied" with the tablet, while another 25% checked "somewhat satisfied."

Carton called the iPad's satisfaction rating "outstanding."
