I use myetherwallet.com It just provides a live link to the most up to date block chain, so everything is still stored in whatever manner you see fit. I have a few hardware wallets and even a paper wallet. You can also access the block chain on an air gaped computer using them. In my opinion it is the best alternative if you don't want to make room for 100gb+ storage to run mist.
