no problems here. in fact i think it helped me quite a bit.

updated in the okinawa airport (terrible idea, i know -but i couldnt wait!) and i think the battery is a bit better. on the way to okinawa i watched three eps of Nip/Tuck and i had to turn the n900 off to conserve battery for when i arrived.
on the way back home, i watched FOUR episodes and i still had over 50% battery remaining.

oh, mscim is a little weird now. it doesnt show the input method when you type kana, but if i press spacebar the kana appears in the text input box anyway.
