I recently applied the voodoo lag fix for my galaxy s, it made a huge difference as my phone was getting really hard to use.

I am now concerned about something I read about the impact of froyo. It seems that even though froyo works really well with snapdragons and TIs, it doesn't have such a big impact on hummingbirds. If this turns out to be the case (it seems to be at the moment), then people should stir away from samsung and towards HTC,

The N900 is just in a different league. What lets it down is not the apps, nor the browser or hardware etc. It is just that its "phone" features are primitive comparing to any proper phone and nokia is not willing to invest into fixing those.
