I prefer iPhone, it is the most comfortable tool.
If we are in vacation we use it as a navigation system. We tested it in USA and Canada and this year in Israel.
And (of course) also in Europe.
Yes, I am definetely an Apple-fan.
You don't need thousends of apps.
My wife is still using an older one iPhone (3GS) with a prepaid-card. So we are also able to buy prepaid cards in USA...and it works very well.
