LOL - I bought just before the Tab Note and felt the same ...
I had a quick chat with a girl early this year in Seoul about the Galaxy Note. I saw her with it, and had to ask a bit. She loved it.
I've done a lot of work on some of the "guts" of the Note, and man... it's some pretty cool stuff. The new things coming out soon are even cooler.
Basically, the Note is going to take over. The hardware/software integration in it is far beyond anything else on the market. Samsung is going to EAT the competition.
No. You won't be able to do anything like it on your iPad.
No. You won't be able to do anything like it on your ACME Android.
Samsung controls so much of the hardware manufacturing that others simply won't be able to keep up.
I can't say too much specifically as I'd have to go and check to see if it is publicly available information first, and just not that inclined to do so. But do keep your eyes open -- more is coming.
(That being said, we have another 800 lb gorilla to deal with -- I'm not blind.)
