Hmm... People seem to be conflating two concepts... EAC is a ripper... It just takes what is on a CD and renders it into WAV files (basically, straight PCM data in a wrapper) on your computer, and with "secure" mode set, it does it very, very well. It has a hook in it that allow you to specify an encoder that will take those WAV files and compress them to create files of a different variety--mp3, Apple Lossless, whatever.
I think you have to differentiate between the ripping function and the format conversion/compression function. WMP10 may be set up to combine those functions, but its still two discrete functions. You can separate the two functions as well--you could use EAC if you are concerned, and then separately change the WAV files into WMA Lossless files. (The only issue there being whether you will preserve track/artist/etc information in the transformation; I suspect there is a way of calling a WMA Lossless converter from EAC that will preserve the data--that is what I do with iTunes, its automatically called from EAC.)
