Paul Thurrott provided us with some data about is data usage as a guide to see if there would be wild spikes in data usage with Windows phone since it’s so intertwined with the cloud. While there are variables here and the numbers are still jumping around, it’s pretty clear that the usage is generally below that of the iPhone so you shouldn’t expect a jump in data use. Nonetheless, it’s still enough data to warrant the higher 2gb tiered plan. But, more importantly he notes (in the comments):
I have still only dropped one call in five months of use, yes. In fact, you may know that I just spent 8 days on the road, and I made many calls in Seattle and that area, and in Las Vegas, then a call from Charlotte, NC on the way home, and then a few from Boston. Not one dropped call on the whole trip. It’s been night and day, as we say.
He’s using a Samsung Focus (a.k.a my next phone) that replaced his iPhone. Hey Apple, any comment about this? Want to blame the network again?
