Viewsonic G is the nearest thing and its severely crippled if left stock.
The Nook and Galaxy tab's are great for rooting and dinking with but have a very small screen.
An Android tablet that is a direct competitor to the iPad has not yet hit the market. Tons of reviews of vaporware...but nothing that you can actually go buy.
My ideal tablet would be an iPad with some kind of open source market, where people can freely submit code to an "app store" of sorts, so that those who want to can access this subset of applications. Like some kind of Jailbreak system... :hmm:
