The keyboard is retarded.
like, obama-bowling retarded.
The keyboard is always a downside on a tiny computer, and the dell mini 9 is no exception. There are some workarounds that you can do to make it not so horrible.
I've already rebound "change focus to another window in the same application" (normally Cmd-`) to Cmd-Escape, as that is usually front row and there is no way i'd ever need to run front row on this machine.
