Query: Better size than 4th gen

I bought this for my husband for Christmas. He's training for a marathon, and he's making use of the Nike website for runners--tracking his runs on his iPod. He was using a 2nd gen Nano, but he needed a newer one with more memory. He also didn't like the long, thin shape of the old Nano, which is similar to the shape of the newest Nano (4th gen). We were both happy to discover that we could still buy a new 3rd gen Nano through Amazon.I think Apple needs to reconsider the size and shape of the iPod Nano when designing the next generation. The square 3rd gen fits more easily into pockets, armbands, etc. for people who use their iPods during athletic conditioning.
