Do you use your thumb or finger to text, I am finding it really difficult with a touch screen compared to buttons??

Thumbs. It does take some getting used to but now that I'm used to it I'd much rather have a touch screen than keys.

Thumb, and both thumbs when in landcape mode. It feels odd at first but you soon get used to it and now if feels completly normal. I have a HTC Desire and the predicitive text is brilliant and I can quickly type emails and texts with both thumbs, plus if I get fed up typing I can always speech to text

Depends:

Portrait mode - middle finger
Landscape - both thumbs

On my iTouch I almost always use my right index-finger exclusively in portrait-orientation, and have got used to tapping at a decent speed with it (with all auto-correction turned off, as I found that was more trouble than it was worth-- much better to tap correctly in the first place).

I rarely use the keyboard in landscape mode, but I remember when I had a Psion 3a with a proper keyboard that I always used the two-thumbs typing method with it.

it all depends.. if I'm not in a rush and just chilling then my finger... if not my thumb/s

Thumbs.

Depends

My current Samsung phone is a resistive touch, so mainly thumb, but with my iTouch and its superior touch screen, finger and thumb as needed

I use my johnson. Is this not what everyone does?

Thumbs

Always fingers but if only have one hand free (then thumbs but very slowly). I find fingers much quicker.

Index finger on my left hand and thumb on my right hand. I find it far quicker than a phone with buttons, but it depends on the touch screen. My first touch screen was a samsung tocco, god awful phone and then I got an iPhone, it was a whole world of difference.
