If you could have only three electrical appliances in your house, what would they be?

A laptop is no doubt the first thing that pops into my mind when it comes to survival: it connects you to everything, combines other useful gadgets from the house - the possibilities are endless. The stove is another essential piece of equipment, because I like cooking and can't survive on a diet of raw food or on eating out for all three meals. I also need lights, because my nocturnal senses are not up to scratch; not just yet, anyway.

It's hard to imagine life without technology. So if I had to choose, I'd pick a fridge, air conditioner and a computer. With an appetite like mine, a fridge is essential. It would keep my ice cream cold and yummy. Second, an air conditioner: I can't imagine living without one. Third, the gadget that can do everything - a computer. It can replace a lot of the other appliances I use in my daily life, such as phones and digital clocks.

For me, it would be a microwave, a computer and an air conditioner. I would get a microwave so I would be able to cook food and not starve. I would choose a computer, because it would keep me entertained. I'd be able to surf the web, send e-mails, talk to friends on Skype and play games. Lastly, I'd like to have an air conditioner, because then I could adjust the temperature and make sure I felt comfortable.
