Technically speaking there's really nothing wrong with this keyboard. It feels good to type on, it sits nice and flat which helps preserve your wrists, and it's attractive, but as far as dollar to performance ratio goes it's pretty 'meh'.
There are no real options for adjustment, so if you prefer a more angled keyboard then you are SOL. It's responsive but overall it's fine, just fine so don't expect anything revolutionary. The biggest fault is that this thing is really expensive for what you get. If you must have an Apple branded keyboard then this works well, otherwise you can find much better bang for the buck. One very good quality is that it's very quiet, so unlike with a mechanical keyboard you will not keep your spouse/roommate/etc up all night.
