Prices go from 0 to $1.99.
By the way, digging a little bit in the past (March 2008), I've found an interesting rumor from Apple about a tablet from Mac:
A little birdy tells me that Apple will announce a 12 or 13-inch tablet in the fall of this year. Most likely in the September or October time frame.
That was rumored one year earlier as well (January 2007).
I could go even further in the past, but the good news seems to be that this time, eventually, we'll get the mega tablet from Mac on the next Fall... maybe.
