There are two devices in question here - the Galaxy S and the Galaxy Tab. Both of these are touchwiz devices. Samsung claims that adding TW to ICS will require more hardware (in particular, RAM) than these devices have. One option would be to remove TW - the nexus s and galaxy s are near identical in hardware spec but the nexus s will be updated to ICS. The main difference being the nexus s is non-TW. However, for samsung, this is not really a viable option. Going from TW to ICS is a major change - things work differently under TW than stock android. Their best "option" (ignoring costs) would be to find a way to minimise the amount of RAM TW uses and enable ICS on these older devices. The galaxy s has already received froyo and gingerbread upgrades. What do people think is an "acceptable" upgrade timeframe?
