Flying cars waiting for you in future

I have a dream for long time, past 10 years or so, when there would be little aircrafts available for use like we use two wheelers, personal cars. May be one day I would design a light weight but sturdy air travel vehicle for myself so that I can roam above the ground, high up in the sky like birds and see the world as it looks from up there. May be I would be able to own some such vehicle in future, if I lived by then. I expected small personal airvehicles to be available for common use surely by 2050. But this slashdot article seems to suggest, it could be even possible before 2040, may be by 2030.
