I need to buy an external HD for me to use Time Machine. I've been traveling alot lately, so I was thinking of getting something similar to the Time Capsule where I could get wireless (distant) connectivity. I would like to leave the HD home while traveling, since I already trashed 2 HD by dropping them. Has anyone used this: http://www.bestbuy.com/site/olspage.jsp?skuId=9234321&type=product&id=1218064407075 There older reviews but these are from the older models. Any other suggestions?
