This especially *screams* for re-considering certain design decisions that we inherited from Smalltalk. 256MB of RAM makes it hard to argue for complex schmemes to save some a little ram. (Compact classes, for example). How would smalltalk look like if it would be re-designed with the same philosophy that they used when there where just 256Kb in the Alto? This is a fun comparision: http://www.raspberrypi.org/ vs http://en.wikipedia.org/wiki/Xerox_Alto 1) Price. $35 vs. $35000 (est, not adjusted for inflation). x1000 2) RAM 256MB vs. 256Kb (max was 512, at the end). x1000 3) CPU 1MIPS? not sure. Vs. 700Mhz ARMv11 x 1000 (?) + 3D and MP4 decoder So one could argue that it's a factor of 1 Million considering price and Performance together... Marcus -- Marcus Denker -- http://marcusdenker.de
