That's according to news and rumor site Fudzilla, which claims to have gotten the info from a "nice talkative chap from LG" presumably at the Mobile World Congress. The rep indicated LG plans to price the 32GB tablet between $700 and $800.
We don't know if that's the trend Honeycomb tablet makers will all end up following, but if so, it's going to be difficult for Android to overtake the tablet market. The hardware is better than what you'll find on an iPad, however the upcoming iPad 2 will at least partially address this. Plus, Honeycomb tablets will be going up against RIM's PlayBook (QNX) and HP's TouchPad (webOS).
How much would you be willing to pay for a Honeycomb tablet?
