Buy a voice recorder for meetings. I used to do a lot of handwritten notes on my iPad as well.

I don't know if its still available for iPad (I have the 1st iPad) but I used to use an app called AudioNote (I think).

With this app you could record audio, and any notes you took are synchronised to this audio. It was super useful...

Apps like Notability [0] do this very well these days. You can combine text, pen and audio input, though I'm not sure if the audio is synchronized.
