haha welcome to the world of 5800XM  i been smsing while driving since i got my tube. Alphanumberic sir. Keypad button as big as your finger.
When you master alphanumberic all u need is the word in your head and u know where to touch to create the word. I see only to confirm receiver and message

I also sms while driving but the phone is on the car mount.
But 1 thing is the "backspace" is sensitive. I kept pressing when wanted to press the right arrow.

Can..  but not as good as Aspire laa.. I have to hold my phone near my steering while driving so that i can see both the phone screen and the front windshield.. 

p/s: hope you can pm me my tracking number for bulk 5 soon bro.. thanks 

Are u telling us u neverever touch your phone while driving.  Drive phone safety first keep phone in back even sms ring even phone call cannot cannot i must not touch my phone for the sake of before i kill someone. 

Well, it is dangerous to type on a touch screen phone while driving.
But oh well, like aspire said "practice makes perfect"

I don't think I'm a hero by saying that. If you insist on thinking that I'm a loser, go ahead. I'll be gladly to accept your compliment.
But for me, if I don't sms, I will practically get sleepy especially during the heavy traffic hours.

Anyway, those are opinions from me.
Peace 

Erm the ca-126 cable's micro USB is normal micro usb or 5800's port?
Im using mediacoder and xilisoft video converter ultimate.
Mediacoder is free and xilisoft is a shareware (need $$ or ... u know)
hmm the settings i use are:
MP4 container
XVid
bitrate: for normal quality or low quality i use 1200kbps, for HD quality (SNSD show etc) i use 3500kbps (no lag at all and perfect clear)
resolution: 640x360
aspect ratio: 16:9
crop: disabled or expand
audio: 128kbps LAME mp3

The file size is bigger if you select high bitrate, but the higher it is the better the quality. (no lag)
