If you keep a few of the important points in mind the hardy kinds of orchids really are pretty easy.
A lot of the windowsill type orchids (Oncidium, Cattleya, Phalanopsis) are really easy to keep so long as you don't overwater them. They often do best if allowed to dry out between waterings. It is important also to use good water. Tapwater in most areas is too hard and contains other bad stuff, such as flouride and heavy metals. It is usually better to use RO or rainwater.
Some of the little hardy terrarium miniatures are super easy and seem to thrive on neglect as much as anything else.
