I wonder who still have the time to download those pc wallets,cause it's old stuff now, mobile wallets are much easier and faster to use rather than pc wallets, I think mobile wallets should be made(developed)first, even before they consider making a pc wallet, cause just as you said there are more mobile phone users than pc users, also you can take your phone around while your pc is normally at home, imagine if you want to make a transaction and it's not a Mobile wallet so you have to run back home to use the pc?.
Hardware wallet is the best, but if you can't afford it, you can use Electrum Wallet. Electrum is an open source wallet and it's completely free, like your own bank. Never hold on to Coinbase or any other exchange. This is very risky. Electrum wallet is best after hardware wallet.
Yeah hardware wallets are the best, but mate OP is actually talking about new projects that only create pc wallets rather than Mobile wallets.
