Agreed that that the IPP and SB both have note-taking capabilities. But that's pretty much where the comparison stops. The IPP is just a bigger Ipad w/added pen. It's still just an Ipad where you can install apps. The SB is full blown laptop capable of installing 1000's of application not apps.
If the OP is mainly interested in battery life and note taking, I would recommend he stick with the IPP. The SB is overkill. If he needs a real laptop, then the SB is right choice. No sense in purchasing a Tesla when a Prius will suffice.
Wells there's the rub. In my case they both cost the same, so which is the Tesla and which is the Prius
They both have a lot of apps you can install, that's not really a distinction. They both have great battery life. They both have great "on the go" portability with the IPP winning out with optional LTE.
A lot of things you can do on the SB are easier on the IPP. Case in point, replying to your post. Couldn't figure out how to do that on Tapatalk on my SB, but easy as pie on my IPP. There are countless other apps that are touch friendly and easy to use "on the go" versus the SB relegating you to mouse or precise finger taps that are not as easy on the fly.
I'll be using the SB, get frustrated with something and switch over the the IPP. Then I'll be using the IPP, get frustrated with something (like not being able to share a OneNote Note) and switch over to the SB.
It's a constant back and forth cycle for me
. But they each have strengths and they are both beautiful devices in their own right.
At this point, for me anyway, the IPP has a bit of an edge due primarily to the betting inking results I get. Because the contact point of the pencil tip is right on the paper, my writing is much neater.
I'm actually leaning towards just keeping both as I'm not sure one can really replace the other.
