Buying an ereader: Kindle, nook or Sony Pocket Reader

[pslasher.livejournal.com]

Hey everyone! I’m probably going to be buying an ereader for Christmas and have narrowed it down to the nook, Kindle or Sony Pocket Reader. But I keep debating over them and thought I’d see what the users have to say.

Amothea says that the Sony Pocket Reader supports collections and has excellent sorting abilities:
My Supernatural collection has over 300 stories but I can within the collections sort by date, author, title, and etc. And once I have the title or author selected it gives me a list A-Z so I can jump to the author at the end very quickly.
Do the Kindle or Nook do anything similar, like support the tags from Calibre? I prefer the look and feel of the nook and Kindle, and they are less expensive than the Sony, but this feature is excellent.

　
Kindle: I REALLY like the long battery life and light weight of the 3G but I have a few questions.

1. I think I heard that fics uploaded to the Kindle from Calibre can be tagged and the Kindle will display those tags and the related ebooks, but I’d like that to be confirmed.
2. Can you browse the web on the Kindle? I think I’d really use that feature for finding new fic that I want to put on the device, and I know the nook can do it.

　
Nook: I LOVE the ability to add extra storage, and to browse the web. I think I’d use the web browsing to find new fic often.

1. Does the nook (black and white) have the ability to create My Shelves like the nook color? Can you sort through books in a collection by author, title, ect?


Is there anything I need to know, good or bad, about the devices? I think I’m leaning towards the nook, but I’m still not sure. I’ve got more thoughts about ereaders here.
