Personally, the only thing I'm lacking with the Note 2 is desktop power. I sold my laptop (mid-2011 MacBook Air 13), tablet (3rd-gen iPad) and some ephemeral smartphones (Galaxy Nexus, Nexus 4, iPhone 5) to end up with the Note 2. I find it sufficiently accomplishes the tasks I'd do on these devices, while I have a relatively high-end desktop to handle the rest. The $600 I spent on the Note 2 actually saved me a ton of money.
If I had an iPod or standalone MP3 player I'd no longer need that, too (80GB of overall storage).
Me, too. I have a Nexus 7 that I like for reading ebooks. But otherwise, the Note 2 totally does it for me except for usage where I need a productivity app that only works on Windows and really needs a a much larger screen, keyboard, and mouse.
My only complaint is that I wished Samsung made an extended battery and extended battery back cover, so that it would be a standardized size and easy to find cases for. I would love to double the battery life on it given how useful it is for so much. It really needs the battery life of a good phone and a tablet combined.
