Does it matter which end you insert first when charging the iPad2?  I thought I read that you should connect to the Pad before connecting to the computer or the charging block.  I can't find confirmation.  It sure would be convenient to leave the charging wire connected to the power source and just plug in the PAD when I need to fill up.
Insights appreciated.
