I have the FiveSpot and have a love- hate relationship with it. The battery life is terrible and it seems as if it goes from warning to out of juice in no time, so it may as well not warn you. You need to be prepared to re-charge at all times.
The operation is quirky. For example, you need to press the switch for 10 seconds (an eternity) to turn it off. Sometimes, the power light stays on and goes off when you release it, and sometimes it goes off while you are pressing the switch.
On the other hand, coverage has been good and it came in handy numerous times. For example, my husband was in the hospital and wifi was not available. He used the FiveSpot and it made his stay bearable.
My husband and I each got iPad 2s with 3G, but have not activated it yet. My FiveSpot contract is up in August and, between now and then, we need to see how we use it and how we use the iPads and then decide what to do.
