The ICD Ultra, Notion Ink Adam and other Android-based tablets have been pushed back due to flaws in the NVIDIA Tegra processor they use, a rumor claimed today. The dual-core Tegra 250 at the heart of these and a Compal 7-inch tablet allegedly has "serious issues" of reliability and has pushed back launches until August at the earliest. A SlashGear tipster claimed Compal wouldn't ship its reference design until mid-September, while ICD and Notion Ink wouldn't ship until the fall; ICD's Ultra and Vega wouldn't arrive until October.
