OK, then let me ask this in conjunction:
I was looking at getting a 7" tablet, mainly to use as an eReader because my Kindle3 doesn't handle my programming books. PDF's look like garbage on it, and they don't convert to .mobi well. At all. Seriously, if I had the time to write an app that would convert them well, I'd be loaded. Even if I only charged $.50.
Taking that in to consideration, would the Note be able to handle that? I was worried about the 7" screen size being potentially too small. Is 5.3" going to be too small?
I'm not tech savy enough to know about file conversions from .PDF to .mobi, and all of that. I can say that I have had no problems reading, viewing, or editing any documents on the Note so far.
In regards to your question about whether 5.3 is too small as eReader, I don't think so.
Prior to owning the Note I carried the Epic Touch GS2 (which I believed to be the best smartphone out there), and a Tab 7.0 Plus. I used the GS2 for the usual smartphone features like instant access to email, calendar, and a few games. I paid an additional $30 a month to Sprint for the mobile hotspot feature which allowed me to tether my Tab 7.0. I would use the tablet for viewing Netfix, eReading via the Kindle app, and for typing notes during business meetings with the Evernote app.
However, now that I have the Note, I sold my GS2 for $200, and my tablet for $325, and now just carry the one device.
With the larger screen of the Note I can read email and eBooks with no problems; view Netflix with ease, and instead of typing with one finger like I used to do during business meetings, I can actually take handwritten notes, and upload my handwritten notes to Evernote as soon as the meeting is over.
So in my world the Note has become my all-in-one mobile computing device. I think that's what makes this device so unique. With supporting apps like Dropbox and Soonr Scribble I literally have my office with me all the time.
If you decide on the Note, I can almost bet that you will not want a mere smartphone again. You'll get so used to the screen size, and the added convenience of an all-in-one device that using anything else will seem strange.
Let me just add, I can see the need (maybe in the future for me) for a stand alone 10.1 tablet for maybe around the house, but when you are out and about everyday, the Note is the way to go (in my humble opinion).
