Did you try Parity light ethereum client ? Ethereum is very easy to use, my grandma could send money with it, please dont take your bad experience for a generality.
"Practical use total bullshit" What could be the practical use of a world scale decentralised computer ? I wonder ? Ethereum wont be replaced, smart contracts tech is here and will stay.
Please supply links. I have myetherwallet with metamask as well as geth. Happy you have good experience. The normal transfer of funds is not my issue. I want to do with Ethereum what it promises, build DAPPs or Tokens and sell them etc.. THat's causing the headache, please help if you have experience. Thanks.
