What's the ROI on ASIC?
I was looking at some websites which tells you how quickly you will recover cost and it looked like I will be doing break even in 5, 6 months. Is this for real? I mean if you can recover your investment in 5, 6 months then shouldn't every one be doing this?
Plus those countries where electricity is free have quite and advantage in case of ASICs.

Is ASIC like a dedicated server which you can buy and then use online to mine or it is actually hardware that is actually shipped to your address which then you can use to mine?

I just installed bitcoin-q and guiminer for the first time. I am connected to "slush" pool.
When I run guiminer it starts with around 4mh/s but after a minute or two drops to 32kh/s. Is this normal?
I am running it on laptop with built in Intel HD Graphics which I know is pathetic but I am curious as to what causes it to drop to 32kh/s after it starts at 4mh/s?

My second question is, I have saved my wallet using bitcoin-qt and wanted to know how often do I have to keep saving wallet. Do I have to do it daily or will it do automatically now that the first time I have saved it?
