Here's the first in what I plan to be a series of mini interviews with Windows Mobile Users in Japan. I was surprised that I unearthed a few issues that already have solutions, but to give an accurate picture of what user's are experiencing I left Dave's answers as they are and posted my thoughts below. Please follow up with thoughts of your own in the comments thread.

Is this your first Windows Mobile Device?
Yes
What device are you using and how long have you had it?
I am using the X02Ht and I have had it since the first day it came out here in Tokyo, September 22, 2007.
What's your experience so far?
Honestly, it's been life changing. I have a lot of meetings outside of the office and I like to keep up with emails or make notes whenever I have a free moment so I would end up lugging my heavy laptop all over the place and would feel sore and exhausted by the end of the day. I feel much better leaving my laptop at the office and just checking on my device every couple of hours. My shoulders and back are thanking me!!
What's your favorite feature?
I haven't utilized the calendar yet so I would say having the ability to check my POP email accounts is my favorite feature.
What do you most dislike?
The keys are a little small for longer email messages, the office products like word and excel are missing a few basic functions that make using or viewing them a little bit troublesome. Although I don't mind that much my colleagues seem to dislike the volume of my ringtone. Three of us took a crack at trying to figure out how to drop the volume but there doesn't seem to be ringtone volume control.
What feature do you wish you had?
lol, this is dreaming but a Sync solution for my Mac and a Sync function with gCalendar.
Any other comments?
So far, so happy ;) Would definitely recommend it to people who hate lugging their laptops around town and who have a slight addiction to checking emails like me.
