user interfaces

i've switched phones recently, after almost 3 years of literally living out of my n-gage for communication. my new phone, o2's xda zinc, is a real wonder (in my eyes atleast). the touch screen, windows mobile, and the qwerty keypad make for a (unsurprisingly) computer-like experience. however, since it's small and fits in my palm, and it feels like a phone too.

for the first time in my life, i'm actually finding myself occasionally confused between user interfaces.

a few examples:

at my pc, i wanted to right click on a file, but instead i held the left mouse button while pointing at it, the way i would on my phone...and was surprised when it didn't work out as expected. my first surprise was when nothing happened and the bigger one was when i realised what i just did!

on my phone,when wanting to type 0 (which is on the "p" key), i pressed and held the key down (they way i would have on the n-gage), instead of using the "symbol" modifier key.

words of wisdom: the more similar two things are, the more confusion they create.
