If only MS Reader did a version for Palm! The fact is that very few people would move from Palm to PPC just so that they could read MS Reader ebooks. If they did a version for both OS's, they could sell more books.
I've ended up having to have several different readers on my pda so that I can read the ebooks that I've bought. I don't really like any of them, they don't have the functionality that I've grown used to with HandStory, Plucker and especially iSilo, and there are problems with the DRM, especially with Adobe.
Adobe Reader for Palm OS is bad enough as it is (and I now use Repligo instead), but for DRM books you're stuck with it. And the problem is that ther are many specialised books that are only available in MS Reader or Adobe formats. The verification process with both the pc and the pda keeps going wrong, and I've now ended up with about £100 worth of books that I can't read. Emails to Adobe have had no response. It's an absolute disgrace

. They really need to change their system. I can see that there does need to be DRM, but a system like that used by eReader is much easier to use.
Another issue, of course, is that you can lend someone a real book, but not a DRM-protected ebook. I wouldn't mind if they reduced the price correspondingly.
What we really need, of course, is a common standard for DRM-protected ebooks. Maybe mobileread should start a campaign?
