We had a variant on the sandwich toaster that could make small pies, the Breville Pie Magic, quite a good piece of kit it was.
My gran had a travel kettle for that purpose and has only recently stopped using it, before that she had a Russel Hobbs Two Cup, but she found the on off switch got too stiff to push easily.I use a George Foreman grill for toasted sandwiches, works well and is very easy to clean.
I think Teasmaids lost popularity as central heating became widespread - if the whole house is warm it's easier to nip downstairs to make a brew and take it back to bed with you. It's only if the house is chilly that there's an advantage to having tea without getting out of bed.
