It seems that Acer is having a bit of trouble getting Android 3.0 to work properly with the 7-inch display, because Honeycomb was designed for a 10-inch screen.
What's more, applications are proving a bit of a pain, with many Honeycomb apps "incompatible" with the 7-inch device.
Bit of a wait
The same problems are likely to abound for HTC, which promises an imminent Honeycomb update to the 7-inch HTC Flyer, currently running Android 2.3.
Iconia Tab A100 fans will be left waiting until August or September for Acer to iron out these issues.
It's not been a great month for Acer; the company has also had to delay the 5-inch Iconia Smart Android handset until July, although that's thought to be down to component shortages rather than any Android issues.
