Cheap Smartphone+ Premium Tablet = Perfect Combo?

I mainly need a smartphone to sync my contacts and reminders, receive notifications and have a quick peak at them. The phone doesn't need a high resolution, a large screen size or a lot of processing power. It can be a cheap Android phone or an old iPhone for example.

This is because I find for everything else a tablet is better suited:

  • browsing the web
  • viewing Word documents and PDF documents
  • reading RSS-feeds, read-later apps
  • watching videos
  • all kinds of apps and games
  • ...

It is perfect for the couch, the desk and fits nicely in a bag, backpack or jacket.

Does anyone feel the same?
