Get Apex Launcher, its the best one for ICS.

You can also install MIUI on top of ICS
(launcher, lockscreen, notifications dock, system settings, universal theming, music app, internet browser, file explorer)

And you can also change the icon grid in the launcher, make it 6 x 6 or whatever and you can have them "stick" instead of "auto-align" like iOS. Frankly MIUI is better than stock Android in many ways, there's just no need for Homescreen+AppDrawer, when they can be fused together. Widgets go great around icons trust me.

The only thing MIUI is missing is a revision. It "needs" one after ICS was introduced because v4 didn't bring anything new to the table. Improvements include: using the stock "Folders" mechanism in the Launcher, improving the design to see Widgets (like ICS), and having an optional/deletable AppDrawer for those keen people.
