I tried the Nexus 10 and returned it. Unfortunately, Android is still not ready for primetime on tablets. When/If it is, I will buy one. For now, I too LOVE my iPad2 and thinking about getting an iPad5 if the weight is reduced to 1 lbs as rumors have it.
On phones though, I switched to the Nexus 1 and have had them all since then. Love them!!!
