640K ought to be enough for anybody.

I bet that's part of the reason why microcontrollers, embedded programming, and retro computing are all popular hobbies these days. A return to a simpler time, when programs are compiled to a few kilobytes and run as fast as the hardware allows. Graphics? Unicode? Who needs 'em, just a stream of ASCII and integers for me thanks.

Unicode is a must in a human facing application, even in those countries where English is spoken by the majority of people.

I'm waiting for restaurants I can telnet into to get the menu (because SSH is too heavy).

640K is enough to read a menu.
