hi, i'm buying ipod nano to be used generally for watch only, as i have the classic, and iphone. i have a few question though and i hope that someone can answer me or at least direct me to a thread or web that have discussed about this before. - what the difference between the 2010 and 2011 nano ? - if i use for watch only, how long the battery will last ? - what brand of bracelet is the best one outthere ? i prefer bussiness man style not those fancy one. - is the screen scratch ressistant ? or i better off putting a screen protector ? so far thats my questions, of maybe you can give me inputs on using the nano as a watch, is it recommended or not. and i guess i better off buying the 8 GB for my needs or 16 GB ? thank you.
