Should I save up and buy an ipad for $500 or a sidehack (bike with sidecar http://www.walmart.com/ip/20-Impakt-Sidehack-Bicycle/12554957 ) for $274. I have about $80. I get $10 bucks a week and get $5 for lunch that I can keep about 3-4 days out of 5. I have a bike but not a sidehack and an ipod touch so what do you think?
