For PDF documents, I strongly recommend you an iPad plus Goodreader on it. You should also wait a bit and probably get your hands on the Motorola Xoom (if money is not a concern) It is heavier, but has the perfect size for PDF documents and runs Honeycomb. I have seen RepliGo on it but I'm assuming it will be soon optimized for that screen if it was not already.

Even though RepliGo is really good (I have it on my Galaxy Tab), nothing beats Goodreader as PDF editor and viewer. The bigger screen on the iPad also allows you to read the document with few or no page turns. 7" screen are kind of small for PDF documents, at least on my opinion. I prefer 10" for my PDF documents: Kindle DX, iPad.

Yes, there were known issues with wifi connections after NC was released, I personally had some of them: poor or no connection and got disconnected all the time, but that was before firmware upgrade. If I recall well, those were fixed with 1st patch. I cannot make any comments after that because I returned my NC just a few days before that initial patch was released.

Last but not least, be aware that from B&N online store, you could face some GEO restriction problems which means, there are some books that you won't be able to buy or download.
