I'm thinking about getting an iTouch for the apps, checking things online, etc. I have an ipod classic (160GB) for my music, but I wouldn't mind keeping some on the iTouch. Initially I was trying to choose between the 32GB and 64GB versions of the iTouch, but I'm wondering about other options. Are there any devices similar to the iTouch, such as anything by Android, that compete in price and features? (Note: not looking for a phone)
