Wow, I didn't realize that large of a capacity portable had gotten so inexpensive. Amazing, isn't it?
Still, it is roughly 3x the size of my SD card holder:http://www.amazon.com/gp/product/B003G2YZAK/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1
Which is just so easy to keep in a zipped pocket in my pants. With 64 gb cards, that's a lot of storage. I love SD cards and I don't have any issues with them launching or getting lost.
jjj, I know where you are coming from and I'm not disagreeing. About two years ago I had numerous international trips coming up, and I was completely out of shape (53 yrs old then). Fortunately I have the financial resources to buy mostly what I want, so I went with gear that reduced the weight and bulk substantially. For my next trip I'll have a tablet/convertible and thus will be even lighter.
The problem for me is that when I get all tired out, my creativity is out the window. When I have spent all this money to go to Cuba or wherever, possibly the only time, I want to be at my best. Now I'm quite fit (and lighter myself) so it may be a bit different.
Running light is a state of mind, you have to look at every little thing. Being able to go for a month with a single carry on and a small domke bag is just heaven (to me).
All the best in your travels. Bob.
