I agree the decision has to be based on the usage patterns...
Regular phone users should stick with (or upgrade to) Smartphones.
Enterprise phones users (sales/field reps/heavy data users) should go for Pocket PC phones.
I feel right now there is not much confusion..in the future when the devices with varying screen sizes hit the market, thats when the real confusion would begin. Definitely for the geeky ones
What I would like is -
1. for every pocket pc phone edition and smartphone to have SIM card, regardless of whether it is CDMA or GSM. Wish Microsoft could use its influence in this area.
2. the SIM card should be like SD card slot, accessible without removing the battery. This way I can have two devices, different screen sizes, and use one depending on what I am doing, and have one phone number.
