"You can bring an ADDITIONAL under seat bag if you’re an easyJet Plus cardholder, FLEXI fare, Up Front or Extra Legroom customer, or if you’re travelling with an infant (under 2) on your lap."
The stuff you can bring on if you aren't a cardholder (etc) is much more limited, and certainly doesn't include a laptop.
"As well as your cabin bag, you’re allowed to bring some extra things into the cabin. e.g. umbrella, overcoat, crutches, walking stick, one standard shopping bag of duty free goods bought at the airport"
