Your wallet is just a keypair. Once generated, you can move it to a USB stick and delete it from any hosts. Then, just use the USB stick copy when you want to access your wallet.My vote goes towards the "waste of time and money" belief. This is based on the fact that I don't have time to waste making sure my digital wallet doesn't get hacked and all of my money is wasted.
I don't have anything against it personally, but I have no interest to ever use it since I have zero confidence in it.
