Aperture 3 or save $200 towards the iPad

I'm considering if I should upgrade to Aperture 3. .the only thing I really want out of it is the native support for RAW files from my E-P2. .. i mean, I'm getting by with the RAW converter by Pauwels...

so I guess it's okay! any other features I should be looking out for in Aperture 3 ?? or should I just save the $200 and use it towards my iPad.. $200 is a bit more than 1/3 of an iPad already!!
