Wait ... you want a mobile device clipboard feature to communicate with a laptop, but be integrated in the OS? Which OS -- the device, or the laptop?

> Use the normal copy feature, and Cmd+V has that thing on my laptop.

Any laptop? Without any setup or permissions?

People who write programs can get pretty close to what you want, but not quite as you describe it.

Both OS's. I want to tell my laptop "this is me" and tell my phone "this is me" (say by using the same iCloud account or whatever) and then they just have the same clipboard. When I copy something on laptop, I can paste on all my devices, and vice-versa.

I don't write for either end of the Apple platform (at least at present -- I once did many years ago), so I can't create this, but I hope someone does -- it's an obviously good idea. All you IOS developers out there listen up. :)

As for Android, I've already done it -- it's part of my free app SSHelper:

What do you mean by "in the OS itself"?
