I have both and I’d suggest the IPad if you can afford it. The IPad can do anything a Kindle Fire can do
Heh, I even half a Gateway computer too…2008, with Vista.
Is your router a wireless one? If so, you should be able to get a signal off of it, yes.
Uh, I think you need to pay for any book you want with a Kindle, although if you pay for Amazon Prime, they have this feature that allows you to “borrow” books to read temporarily on it. No idea how wide the selection of books is, though (I don’t have Prime).
Kindle is good for most things. You can get the SDMB on it, Facebook, Youtube, Pandora, Wikipedia…the IPad is bigger, though, it has a bigger screen than the Kindle and a bit more access (for example: on the Kindle, you can only get Facebook Mobile app and use that which allows you to do about three things: Update status, Upload photos, and browse friends’ status’…on the Ipad, you can actually go to the full site and do anything/everything on Facebook that you can on a computer. Of course, all of this is moot if you don’t use Facebook).
The IPad has a camera and can take videos too, which the Kindle can’t.
My suggestion would be to buy the Kindle if you want to spend less. It can do almost everything an IPad can do by way of getting online and the sites you can access. Get an IPad if you have extra to spend and want about 100 more cool features that the Kindle doesn’t have (mostly all little things, though, like the camera I mentioned–stuff like that).
Whatever you do, though, DO NOT do what I did: Get a Kindle and then (eventually) get an IPad…because the IPad will pretty much make your Kindle redundant.
