I currently have a late 2008 unibody 2.4ghz 15" Macbook Pro with 4GB of RAM and a 5400 rpm hd. i was using it on the road for work but now I am using it mainly at home connected to a separate monitor, keyboard and mouse. I don't do too much heavy work. I use Aperture, iPhoto, Office 2011, Plex, Safari, iTunes and the like. Would I be better served with a Mac Pro since I am not utilizing the mobility of the Macbook Pro? The iMac is out of the question since I have room for my one monitor which is shared between a Mac and PC. My main complaint with my current setup is that it is not too snappy. It takes time to load apps and perform certain operations, I'm have a feeling most of it is tied to disk IO. I went to an apple store today and tried out the current models of the Mac Pro, Macbook Pro and iMac and just did some application opening and closing and a few operations. They all seemed to behave pretty similar (I expected the Mac Pro to be faster but I guess for what I was doing it didn't matter. So the conclusion I am coming to is that the increments in processor speed between the models didn't seem to affect the performance of the apps I am using. So is it valid to assume that I should go for an SSD in my Macbook Pro and forget abt upgrading to a Mac Pro for now. Are there any other benefits that I'm missing?
