thanks tom. i started reading this thread and learn a bit that i wasn't aware about. probably the most useful is your comment about renting online mac time. strange i thought, strange way to say rent a mac computer. did a search and discovered there is actually this service for pc users. i guess i really got to get out more often.
i've lamented for awhile the absence of ibooks on a pc for the obvious reason that i want a larger audience. my solution has been to author the must have book that would make everyone want to buy an iPad. yes i am delusional, but i did have a fall back plan to pray every night for the ibooks software on the pc. i still think that might be possible coming but not sure i will e alive to see it.
fall back plan #2 is to investigate another authoring system from adobe, which gained some prominence in my spare time, however little there is because my favorite past time is watching the grass grow. but this looks like a great alternative for when i am beseeched by my loyal customers, all two of them. but now i can suggest rent a mac online. it's cheap!
i am assuming that this service would be good enough to read a multi-touch ibook and seem to the user that they are really on a mac. have you ever done so? thanks again for mentioning it.
