That's an idiot's argument. Did you ever own a 486 back in the day? Did you ever buy a newer computer, even though the old one did its job well? I want what I liked in the N800--but newer (faster, more RAM, more capacity, etc.) not a whole NEW product like a phone (which I prefer to separate from my computer).
What does the Droid give me that the N900 couldn't? hehe.. you're serious, aren't you? For one--the Droid is ACTUALLY a phone--it's stable and MUCH MUCH more featureful as a phone. You only need to search the forums to find out how lousy the N900 seems to work as a phone compared to anything else.
I prefer two devices--one is a phone.. which is NOT my computer (hence stable and not hacked and not liable to crash and I can feel comfortable with tinkering on)--one is a computer.. which is where I'm much more free to treat it as a computer.
