tawan, would you rather have a fully-functioning, stable tablet running ICS (or HC until ICS is stable) or a crippled, unstable device running an untested OS?
I thought so. Be patient. Acer is ensuring the OS will work with the HW and is making sure everything is functional so we can all have the best "out of the box" experience with the new software. This impatience is part of the reason everyone complains about buggy software. "Oh, so-and-so has it already? WHERE'S MINE?! I want it NOW!" but it still must be PERFECT. Chill, we'll get to taste the ICS goodness in our time. Just think of all the people buying unsupported Chinese tablets in the US that are still running GB or (gasp) FROYO!
