It's funny, people are either passionately for or passionately against this tablet for some reason. Either it works for you and meets a real need, or you think it is stupid and junk because you don't need what it does.
For the record, I LOVE LOVE LOVE this tablet. I have access to ipads through my work that I could have for free. I tried them out, but they just didn't make sense for me. Not enough productivity help, and most things seemed a bit gimmicky. Yes, it's nice to email and do my calendar on, but really to carry a larger device just for those things I didn't see the point.
The note, however, let's me do a lot more productivity stuff that I need to do on a daily basis. Handwriting notes during a meeting is crucial. I do a lot of one on one meetings, and writing with a pen is a lot more natural than typing on a tablet screen. That alone makes it worth it for me (since I can never find where I wrote my notes in a stack of a dozen legal pads.) Marking up pdf or office files for revision is also a lot more natural with a pen.
But then add in the multitasking, and it is even better. Running apps side by side is a huge plus.
It was good when I bought it with 4.0, but with the recent update to 4.1 it is even better. Multitasking is better and allows you to use more apps than you could when I first bought it. Another feature that I originally wished it had was the ability to handwrite a note and attach it to an event on my calendar. Now with 4.1 I can do it. So I take notes during a meeting, and then I plan when I'm going to follow up on my calendar, and I can attach the notes I took directly to that appointment. For me and what I do, it's a beautiful thing.
Yes, the screen resolution is lower than the ipad. I have yet to hear a compelling argument why a 10" screen needs to be higher than 720p. I watch videos on it all the time. It's fine. It's a tablet, not the multimedia center of my home. It doesn't do surround sound either, but who cares? (just a note though, the speakers do actually FACE you, so you can hear them without cupping your hand around the back of the tablet. What a concept!)
Another great use - splashtop whiteboard app. I use the note to remote control my desktop. And with the whiteboard app, I can write on the screen for presentations, highlight and underline, and the pen is precise enough to actually make all that useful. The pens for the ipad are clumsy and clunky and lack the precision to make that actually valuable.
A lot of people want to write this thing off (with their clumsy aftermarket ipad stylus, of course) as useless based on the specs - but those of us who use it on a daily basis tend to love it. It just depends if it meets the particular needs of what you want from a tablet. For me, it is absolutely this over anything apple has made yet.
