Practical answer
Should I use a tablet instead?
A tablet is a strong smart-access device precisely because it's awkward to carry.
A tablet does nearly everything a smartphone does, and is too large to live in a pocket. That inconvenience is the feature.
- WhatsApp, banking, email, and travel apps all run well on a tablet.
- Wi-Fi-only models cost less and keep the device tied to places rather than following you.
- Give it a home: the kitchen counter, a desk, a shelf.
A tablet that ends up in your bag every day is just a bigger smartphone. Where it lives determines whether this works.
