>A rail solution allows you to read, a bus throws you around everywhere and makes you sick.
I got exactly the opposite impression the first time I rode a tram in my life. The tram is really really shaky and the connection with the overhead line is flaky, leading to all sorts of strange noises.
My experience has been the opposite: every vehicle on rails has offered a superior ride quality to every vehicle on rubber tires. I can't read on a bus, but on a train it's no problem.
Buses meant for right-hand drive markets like the UK, Australia and Japan are (with very few exceptions) shaky, low-entry configuration two door junk, or double-decker one door junk.
If that's what you're used to, even the most rickety light rail system will feel luxurious by comparison.
Left-hand drive low-floor buses with three doors, and articulated models with four doors, which are intended for the European market, are as a general rule much more comfortable. If the buses you normally take fit the latter description, you'll probably find the average tram worse.
