Alright... forgive me, but I need to vent after my week of frustration. My goal: create a scatter plot with propagated error bars (ie different values of error for different points). Alas, as it turns out, this is not possible at all on a mac. [rant] Numbers doesn't even have Error bars, so it was useless. So, I attempted to use Excel '08. Turns out in addition to other features removed, one can not have custom error bars. I had to boot up my old pentium 3 with Office 2003 just to do my homework. [/rant] I love my mac... don't get me wrong. I'm not going to sit here and say I'm moving to Vista over this. But for any university science student looking to buy a mac, this could be a deal breaker.
