In the new Harvey Norman mailer i noticed the Acer Iconia which says available from 20th April
16GB - $799
32GB - $949
It also states that it has a 10.1" screen ( which i guess makes it the A500 not the A100 unless thats a typo)
Other important specs:
Android 3.0 Honeycomb
Tegra 2 dual core CPU
1GB Ram
USB, Micro SD and HDMI ports
5MP rear + 2 MP front Cameras
The 16Gb model will appararntly sell for AU$579 according to PC World Australia so were getting a pretty reasonale price.
