Ah, I missed that, sorry. You can get them locked to Virgin for $80 from DSE, or on ebay unlocked for around $120.
I recently bought the next model along in this series, the Huawei Sonic, which DSE sell for $188 unlocked. Very happy with it, doubly so considering the cost.
For using it as a laptop/computer, the display width is a limitation. At 320x240, that's 53 chars along the 320 edge. 80 chars would be ideal for an xterm (which larger phones can do, with 480x320). Do you think it's usable as an xterm (with a plug in keyboard)?
That was at launch 18 months ago, $99AU now. http://dicksmith.com.au/product/E7324/vodafone-huawei-ideos-... (that's with a 12 month statutory warranty, change of mind policy, etc.)
