Oh, I didn't know Acer laptops running Windows could run Final Cut Pro or Aperture, or any of the multitude of everyday applications people use to make a living that are OS specific. As I said, it is your opinion based on what you think without knowing any of the reasonings around the OPs intended purchase.
Grats on your zero debt, I have none either. I'm also not pretentious enough to tell people how to plan their purchases.
If someone is using a 1.4ghz 2gb ram, 64gb HDD 11" MacBook Air to make their living as a photo or video professional and can't afford a $900 replacement, maybe its time to re-think their career.
And you should try to enlighten others as to responsible use of credit, because ultimately those who don't use it properly cost everyone more $$. It's a big accomplishment to be debt free. You brag about the Mac computers you own in your signature, and you think it's pretentious to express opinion that it's better to save then buy rather than buy then figure out how to pay? LOL..... strange.
