i'm from japan and have bought an HTC Touch Pro, too.
first i was very excited about that cool interface(even if it was japanese), the wi-fi function, and the full-slide-out-keyboard. i thought it was the best phone i could ever get.
but playing around with my touch pro, i figured out, that it gets very slow, if you dont turn it off, because it uses more and more RAM. and besides, the "settings" interface was awful. it was just like windows 95... i played around with the settings, and found, that you couldn't change the language and the lock from windows slowed down my phone a lot.
after few months, my touch pro couldn't connect to the 3G network after i rebooted, so i could not send any MMS with the provider software. so i went to the provider, and they said, i had to clean my sim card sometimes. that worked funnily enough for 2 days. but then it didn't work any more. i didn't want to go to the provider, because i had to wait 1.5 hours, till they figured out, i had to clean that sim card. so i tried to send mms with an other mail software. it worked, and after that, i could send mms with the provider software, too. i couldn't believe it, and rebooted. but then, it didn't work again. i sent an mms with the other mailing software, and then it worked again.
so, when i restart my phone, i need to send an SMS or an MMS to myself, to even recieve SMS or MMS from other people.

but now, using the Touch Pro for 1 year, i'm satisfied with this buy, because i found on this forum, how to speed up and change the language for TF3D. i also found S2U2 so i had a lock, which doesn't slow down my phone.

I'm happy with the Touch Pro.
