I have an iPod 3G which I primarily use for music and podcasts while driving. I am thinking of getting a 4G for sometime video and Facetime as several relatives have iPods or iPhones with FT. I am probably going to get an iPad (a 3 if it appears in March). I assume the iPad will serve my purposes while driving, but it doesn't fit in my pocket otherwise. Can't really afford both now unless I can sell the 3G for a decent price. Advice please. Thanks.
