Sure, the Lynx offers interesting hardware features like scaling, but the games (at least the games I have) are not very smooth nor that fast, worse, sometimes they are almost unplayable because of terrible slowdowns (Xenophobe in some levels for example).
Actually I was a bit disappointed by this system. Don't forget it has 2 dedicated 16 bit chips, (one of which is the graphics chip) operating at a "blazing" 16 Mhz... I don't think the Amiga 500 had any of its chipset running at 16 Mhz ;-)
And the Amiga has 4x more pixels to deal with, too (Lynx screen size is 160x102) ! :-P
