If a tablet is like a phone then in my opinion its just a clunky cumbersome object without phone capabilities.
Without a keyboard, I cannot do any serious work and I do only moderate browsing on a phone, which suits me fine on the go.
If you have a TV at home, can I assume it’s the smallest one available?
The tablet has much more real estate which makes reading and typing substantially easier. I do almost all of my personal stuff on a tablet. Email, surfing the internet, viewing photos, reading e-books. All of these are much more enjoyable on the tablet than the phone. You do you I guess.
