I agree with your view.
Coverage, Qos, battery life, weigh are all more important
factors in keitai than greater speed.
If we compare WI-FI versus 3G in terms of speed we are
completely out... I really consider this comparison a waste
Most of the wider coverage WI-FI versions are not compatible
with a real world handset form factor and usage. Most of them
are still experimental and not standardized (Like 4G) and they
are really more vapourware than a solution.
For the market I can agree with Forrester. WI-FI will remain
a business oriented niche product while bluetooth will be
widespread. Anyway 3G, Bluetooth, WI-Fi are wireless
technologies that have been designed for different purposes
and not to compete.
For my experience:
I personally use WI-FI (Apple Airport) in the office to move around
with my laptop, i sync my calendar and contacts with bluetooth
(Apple iSync and Nokia 3650) and I use 3G (3) data connection
to make phone voice calls (Videocalls are more or less useless
today), access the mobile portals and check the e-mail on the move.
So really I am using 3g, WI-FI and bluetooth and a way that gives
me value but they are not competing at all.
