I am a so called early adapter (which cost me a considerable amount of money). In the years since the PC was invented I bought gear like the Apple Newton (a Sharp-device actually) a Windows CE sub-notebook and even an Archos Gmini 400 portable harddisk media player. Today I totally shifted to the Apple ecosystem and use intensively:

• An iPhone 5s
• An iPad mini Retina!
• An iMac 24"(late 2007)
• An iMac G4 (late 2003 on OSX Leopard!)
• An iBook G4 (late 2005)

Next to that somewhat stranger gadget:

• An I'm Watch smart watch

And as work-PC I use my Lenovo Thinkpad2 tablet

And of course my Moleskine notebook with Wacom Bamboo stylus and since a couple of weeks I purchased an Adonit Jot Pro for more detailed drawing on the iPad. Note taking had shifted towards the thinkpad with OneNote from Microsoft, for my taste even better than Evernote in combination with the active stylus of the Lenovo.
