Hello! I almost didn't post this, because to be honest I'm a bit intimidated by the Kindle thread.

I figured my questions are probably answered somewhere here on the forums, but I wasn't quite sure where to find the answers. So I figured I'd venture out, and hopefully I don't come across sounding too dumb, although when it comes to the Kindle, I'm pretty ignorant.
Lately I've become really interested in the Kindle, although unfortunately I don't have $139 laying around to buy one. I'd consider selling my Pocket Pro, but I wouldn't even know how to go about doing that. Plus, mine came with a faulty on/off switch (won't turn off or go into screen lock, something's just not connected), so I doubt I'd be able to sell it. (I didn't want to send it in for repair because that was my second one - the first had other troubles - and I was getting tired of paying for shipping

).
Anyway, from what I've seen online, the new Kindle looks really nice! I'm trying to decide if it's worth it for me to save up for, or just learn to be content with what I have. I'm sure my hubby would prefer I stay content with what I have. :
So here are my questions. I'm sure I'll come up with others later, but I'll start with these. Oh, and I'll be away for the weekend so if I don't reply to anyone's responses, I promise to do so next week.
I've seen you can do email with the Kindle. How difficult is it to access gmail on the kindle? Does it work well, or is it really not worth the effort? Is it easy to read and write email? Or is it better for just reading?
Since the kindle has that nifty keyboard, I was wondering if it's possible to write some sort of text document? For example, if I was out for the day and thought of something I needed to do when I got home, would I be able to make some sort of note? Or could I write out something in text, then somehow copy it into an email when I had wi-fi access?
Most of my books are in epub, although I have a few in rtf. Would I be able to read them on the kindle, or would I need to convert them to something else? All my books are free books from the public domain, so if I needed to convert them that would be a simple matter for Calibre, I would think.
Oh, one other thing. Does the Kindle have a status bar at the top (or bottom) of the page? And if so, what information is on that? On my Pocket Pro when I'm reading something in Adobe Digital Editions, there is no status bar. When when I'm using CoolReader there is an optional status bar that can display the name of the book, the page I'm on out of how many total, and the time. I find that very handy, as I have a tendancy to get carried away with my reading and forget to take a break now and then to do whatever it is I need to do. But with the clock there, I can keep an eye on how long I'm reading. I also like the page number so I can have an idea how far I am through the book.
I think that's all I can think of for right now. If I have any other questions I'll let you know. I really want a kindle, but I'm also trying to convince myself that what I have is sufficient.
Thanks!
Edit: I just remembered one other question. How are the books displayed in the bookshelf? I've got 200-300 books. Would I have to scroll through all those, or can you put them in folders? Right now I have my books sorted by genre (sci-fi, classic, action, etc) so I've got about 5 pages of genre folders, then my books are in the different folders. Does that make sense? Is the Kindle similar, or how does it display the books?
