I think the poll asks the wrong questions, and so you are going to get the wrong answers I am afraid.

One might think of opting for a fusion drive because an rpm 5400 drive is such a **** option for a base model in 2013 when apple could have at the cost of the average hardback book added at least 32gb of flash for the os and the apps in the already more expensive by $100 base model, but instead they are ruining the user experience with drive speeds from 2003 on a device for 2013.
I would suggest, that if you are up for it, to screw them and not pay the extra $450 the are asking you for this benefit and opt for a seagate momentus xt (has if I am remember correctly 16gbs of flash for the 750gb model, but it could be eight), so you get most of the benefits of the "fusion" at a fraction of the cost, and you stick a case to the hd you got out of the mac and you got yourself a portable drive too. Maybe seagate will wise up and come up with a 32gb hybrid drive too, so then there'll be pretty much close to no difference from the fusion, in that you 'd be hard pressed to have more app and os space than 32gb, and playing music off an ssd makes no differerence. In addition and this is a BIG PLUS the momentus xt is not a 5400 rpm drive but a very fast 7200 drive too, so what you might lose from flash size you gain in speed on the hd.
All, that provided of course apple has not royally screwed us with a custom heat sensor for "apple" drives only, as they did before. (but even so, there's a software hack for that).
