The Deutsche Bank estimated that the Motorola Xoom Android 3.0 tablet has sold just 100,000 devices according to a Dow Jones news report.
The firm estimated the figure by counting the number of users of the new Android 3.0 Honeycomb operating system which is so far exclusively available on the Motorola tablet.
Deutsche Bank said the figure was in line with estimates of 150,000 in the second quarter, calling the sales "a good start" despite coming in lower than street expectations.
A DigiTimes report citing sources in the touch panel supply chain for Apple's iPad 2 claimed that Apple took delivery of between 2.4 and 2.6 million devices in the tablet's launch month.
Few would expect the debut of the Android 3.0 operating system, held back by a paucity of tablet-optimised applications, to match Apple's second generation table.
However the Motorola Xoom being outsold by 25 to 1 is at least some indication of the mountain that the Android platform has to climb before it challenges Apple's tablet dominance.
