The comparison is pretty apt on the surface, however, the Lynx had a really TINY screen. As in, surprisingly small compared to the overall size of the console, bordering on stamp-like. Also, the thing was mirrored with twin sets of action buttons in order to be flippable for left/right-handedness, as you may recall. Of course, if you flipped it, the text and logos on the front was all upside down, and it had no accelerometer (a few decades too early for that), so you had to press two buttons to flip the screen... Heh, those were the days!That thing makes the iPhone look like a first-gen Atari Lynx.
And yeah, Lynx's internal volume was ~50% batteries, and it still lasted only a few hours.
