I've deleted all of it multiple times. It tends to get to a certain point and get stuck, and only get's maybe 1GB per week downloaded.
I've been stuck at around ~62GB for a couple weeks now after my last time deleting chaindata folder for maybe the 3rd time.
I do use web wallet for now. But would be nice to have my own node!
OH! and the one time I tried to use "lite client" it worked, but the fee was 1.0 ETH to send 0.2 ETH.
