computer crashes + viruses

is it to much to ask for a computer that always does what it is supposed to do without crashing,or dragging. and why do they have to be vulnerable to viruses,malware,spyware,and the like? i may be old to say this but i miss the day when the only problem i had on my computer was a typing error caused a problem with my program. I would like to shake the hand of the person that can solve all of the foremetioned problems! it is understood that computers are cheap because of mass production,but would it not be more profitable to take the time to develope a completely well working system? I'd be in line to get one!!!
