I'm considering switching to a Mac (been waiting for the MBP update, yada yada yada). I was at an Apple Store today and booted up Excel on several different machines (MBP, 24" iMac, mac pro). In all cases when I did the standard CTRL+mouse scroll to zoom in, the text became "washed out" looking at anything other than 100% size, essentially like what happens when you zoom in on a low res image. This does not happen on my PC laptop -- the text remains sharp all the way up to 400% (Excel limit). What's going on? Is it because in Windows fonts are scalable and in OSX they're not scalable? I'm really bummed out about this, to the point I'm actually considering going with a Dell laptop.
