Laptop. But to transport it anywhere, I have to take it in a shopping trolley, as it is pretty big.
Thankfully, it has a very large keyboard. I also have a Netbook that I keep at mum's in Dorset, and hate the tiny keyboard, thought it is SOOOOO much better than a mobile phone/iPad etc
Some are born great, some achieve greatness and some have greatness thrust upon them.
The rest of us are a bit crap.
