Lite means ANYONE can mine Litecoins - you don't need powerful GPU, don't need AMD GPU
You can use any CPU you have and mine coins efficiently!
Lite means system will have less hashpower than Bitcoin (because of CPU mining) - not an issue
Lite means faster confirmations of transactions what is really important for any market or shop
Lite means nobody premined coins for himself so we have fairly distributed coins
About supercomputer hostility: just give Litecoin time to grow. Neither Bitcoin was supercomputer hostile at the beginning.
About botnet: botnet issue is solved pretty easy - identify botnet and block IPs. Forever.
Why people keep spamming idiocies about ip? Wake up, do you know dynamic ip?
Now you are going to reply with ip idiocy 2: ban ip range.
Yeah, let's ban a whole nation.
As for "anyone mining", it's bullshit. Try mining with a Atom or with a i7 2600 quadcore... you still need high end hardware.
