I'd rather have a full sized, well-built virtual machine 98% of the time, but there's two cases so far where I have (or will have) a 1UP: Star Wars Arcade and the forthcoming Big Buck Hunter, because of the unique controls. I like my SW Arcade 1UP. Decent quality build material, not pressboard junk, control stick isn't metal but is still solid and heavy, I don't notice any lag personally (maybe that was an issue with older 1UP tech?), the marquee lights up, and it plays all three flight stick Star Wars games. Pretty neat for tree fiddy. I wish BBH was coming out soon, my wife keeps asking me about birthday gifts.
