I am not trying to start a flame war here, I would like a list of valid reasons for updating a traditional, **non tactile** laptop from windows 7 to windows 8.

Apart from faster booting and touch functionality (if your hardware can take advantage of it) I cannot see any reason why one would *want* to upgrade to this new OS.

UPDATE

OK, downvotes and close votes already. I do not want to open a discussion, I just want some concrete reasons why windows 8 is better than windows 7.
