Welcome to MobileRead, nvanygirl.
Seems like if your library offers that many Adobe format books the Sony would be your best choice...
However, that being said, if you want to buy and download books to your reader while you are on a trip.....the Kindle would be your best choice.
As long as you have a US based credit card AND billing address tied to your account, you can download books to your computer and then transfer to your Kindle anywhere in the world you have computer access.
The choice is yours. Enjoy!
