How do I know if a board fits my requirements?

The usual suggestion I give to people new to Arduino is to get a Starter Kit (either from the store or from a local reseller): it contains an UNO, plenty of sensors and actuators and a projects book.

How can I get a unique ID for all my Arduino boards?

Some boards, when connected to a computer, publish their serial number. My Arduino Uno R3 says [16818.451423] usb 3-2: SerialNumber: 85235353137351E02242 Though I'm not sure how unique it is.
