There are a lot of choices for smartphone cases and what works for one person may not work for another. It’s really a personal choice based on your needs and preferences. TPU cases tend to be the closest thing to not having a case at all, similar to silicone cases. The advantage of TPU over silicone, however, is that TPU is tougher, more durable and attracts less dust/lint. I had the opportunity to try out the Cruzerlite Androidified A2 TPU case for the Galaxy Nexus and came away very impressed.
