Fairly or unfairly, Google's Android often gets knocked for having a lagging or stuttering user interface when compared to Apple's iOS on iPhone and iPad. TiPb's previously guessed that this stemmed from very early architectural decisions made by Apple, who had a full screen, multi-touch UI -- albeit it a highly limited one -- in mind from the outset, as opposed to Google who originally had Android set up as a BlackBerry, Windows Mobile Standard, and Nokia competitor that had no need for high performance, sophisticated UI rendering.
