I've used OSX for five years, and had a near-flawless experience (it failed once when my drive died). My Powerbook-G4 is five years old, and has dust from 9 countries (AU, CA, CN, GB, HK, ID, JP, KR, TH) in it. I reboot when the update makes me, and I've had to purchase very few additional components (such as virus checkers, SSH tools, email products, etc).
The Dell build quality, OS quality, integration, and general user-experience would not be so bad if I had not been using a Mac. I would have assumed that every PC did this, but now it highlights what's possible but obviously beyond the reach of Dell and Microsoft, even five years old.
This tumblr is merely to track the little things I need to do every day to get the Dell to work.
