AppleInsider | Acer exec says Apple's 'closed' iPad will drop to 20% market share:

The chairman of PC maker Acer has predicted that Apple's iPad will drop to just 20 percent of the total tablet market when competing options are introduced, due to the 'closed platform' of the iOS operating system.

I'd take 20%. The big thing about being closed is that content providers are more likely to sign up. Hulu "Plus" or whatever it is, HBO and USA's apps, etc, these want the iPad to stay closed.

My real fear (even as a stockholder) isn't that the iPad will die if it stays closed, but (as an open standard advocate) that it'll succeed too well.
