The new imac		They are really expensive, they do not last a life time, there has also been some bad reviews about the speakers, most people will not be able to afford one.
Projector		Bulbs cost alot to replace, you have to keep it clean so it could work probably and you can get clearer picture.
Digital camera		The batteries will cost, as will the lens. you also have to buy a memory card so all the pictures can be installed.
Printer		The ink runs out very easily and to get colour its getting really expensive also it costs to print because of paper. they break easily

software- its very expensive and crash easily
