1- Some type of Solid State Drive (SSD), but I'm not paying big $$$ for one though - I'll just wait until next year for those to drop.
2- A few flash drives (4GB or higher) - mainly to give away as Christmas presents.
3- Maybe an external HD (I have a 500gb already, but if the price is RIGHT - hehe)
4- Maybe a Sound Card for my PC - dunno about that.
