What are limitations of using Atmega8

instead of Atmega328 as arduino's micro-controller, besides less memory ?

Compare pages 1 & 2, see if anything is missing you might want. Atmeg8 http://www.atmel.com/Images/8159S.pdf Atmega328 http://www.atmel.com/Images/8271S.pdf

One difference that may or may not matter to you is that the 8 has no pin change interrupts so you are limited to the two external interrupts this is easily missed when comparing the two - I know I missed it too late.
