It is strange how my iPad has effectively been a YouTube machine for me over the past two years. I have used it for nothing at all apart from watching YouTube on occasion and so I always viewed it as my least useful Apple product.
Fast forward a couple of months and it has become indispensable thanks to Apple Notes, an Apple Pencil and not a lot else.
I decided to start noting down information I needed, mainly for work, using the Apple Pencil in Notes and created a simple template that is copied each day to create a database of data that I can refer to at any time. It sounds complex, but it really is not once familiarity has kicked in. The blank template is copied, I create a new note by tapping the icon with the Apple Pencil and then paste in the template. The note is renamed to the next day's date (using a letter at the start for ordering such as g-231123) and then added to that month's folder.
The end result is a selection of notes separated by month and all in date order, a database of personal and work information that is growing all of the time which in itself is no more useful than paper notebooks.
Where the iPad solution wins is the ability to search for any text that I have written and to see the results come back instantly. This is so quick and useful that it rounds off a solution that means all data is instantly retrievable at any time.
Compare that to the Kindle Scribe, Remarkable, Boox and other devices and it is way ahead with all of the information available on my iPhone and Mac should I need to find something at other times.
If the iPad only had Apple Notes I would probably still buy it.
