alt Hacker NewsResistive touchscreens get a lot of criticism, and all of it is deserved.
Apple has, correctly, recognized that for a touch-first UI, a resistive touchscreen will always feel worse, wear out worse and perform worse than a glass-integrated capacitive touchscreen. This was a big part of how they got their touch-optimized UI to work and feel this good - which was how they differentiated the first iPhone from the sea of contemporary PDAs.
Nokia sticking with the most half-assed touch UI adaptations, Nokia sticking with resistive tech - all of is symptomatic of Nokia either not understanding what Apple's edge was, or being too slow to react to it.
The N900 was never really intended to be a mass market device, more something to attract enthusiast excitement and serve as a reasonable developer platform - so in that respect it being kind of half assed isn't too much of a surprise. The problem was it taking another two years until the (in theory) mass-market hardware was ready and also there having been another basically pointless upheaval in dev experience (the shift from Maemo to Meego, which included changing packaging formats), and in that respect the experience was incredibly half assed.
