After getting fed up with Wacom's ever changing delivery dates, I gave up on them and bought an Ultraslate from Calcomp. (Although recently discontinued, you may be able to find one. There are other models still available for you Windows types.) It has an excellent mouse function, and it is easy to switch back and forth if you must. However, as Allerleirauh says, there is no reason not to use pen and mouse side by side.
