This is probably not a good time for me to answer this because I have just spent two hours trying to get some pictures and some music over on my X, and finally gave up. I think I've messed up my memory card, it's not recognized. I know just enough to screw things up. Now, to be fair, I never did try to put pictures and music on my BB.
But I do miss it a smidgen. I miss picking it up and seeing all my emails and texts all in an instant, ready for me to read and delete from phone or server or however I wanted to delete it from. On the X, I scroll through screens trying to remember where I put K-9, and then scroll through some more trying to remember where I put the text app.
I know I will get better at all this, and I love all it's possiblities, it's just right now it's winning in the battle of Droid X vs Me. But eventually, I will win.
