The "desktop paradigm" you've described is important, but it is important because it is needed to foster FUTURE software development designed with the NIT platform in mind. I certainly hope the primary goal of Maemo 5 is not to enable reuse of existing desktop apps (ugh!). The revolution of the tablets WAS that they hit that sweetspot where: 1) there is more mobility than a laptop (use it while standing in line kind of mobility) and yet 2) you have a decent Internet, online, experience nonetheless. Various aspects are arguably essential (and unigue) to the NITs - touch screen, optimum processing power/battery life tradeoff, UI, etc. Ported desktop apps would unacceptably degrade 2) and are not wanted.
