lol, no you should not mine. It's quite clear you know very little about this. Without expensive mining equipment you will get zero. You can't just take your laptop and a usb miner you bought off ebay plonk it down in a library for a few hours and expect to get some easy coins. Please do some more research before you jump in.
IMO this is the answer you should be looking at, the smaller ASIC's bought few months back "which are still incomparable to normal equipments" won't reach ROI most likely. I doubt the mining profit would even cover your computer consumption.
