Blame the skins: No ICS upgrade for Galaxy S

Samsung: no ICS upgrade for Galaxy S and Galaxy Tab because of TouchWiz:

Samsung has just distributed the worst news of this Ice Cream Sandwich upgrade cycle: the popular Galaxy S smartphone that sold 10 million units last year and the 7-inch Galaxy Tab tablet won’t be upgraded to Android 4.0. The company’s argument is that they lack sufficient RAM and ROM to run the new OS alongside TouchWiz and other "experience-enhancing" software.

“Experience-enhancing”? Really?
