Dear FSL users, I am looking to purchase new computers for my laboratory. The question main question I have is that are MAC's worth the money? I have the option of buying new top of the line macs, upgrading our lab server, or using a old PC cluster. From what I hear upgrading our lab server or buying new MACs are my best options which bring me too my next question. I looked over the time tables (http://www.fmrib.ox.ac.uk/fsl/feeds/doc/timings.html) and it shows that the MAC pro laptops are faster then the desktops? I wanted to confirm this because it just seemed a little weird. If the difference between the mac laptop and a pc server is that small then I was thinking just to upgrade the pc server, however it seems like the mac pro desktop should perform a lot faster than the laptop. If the performance is that much better I was considering buying the macs. Another consideration is that most of the people in our lab are longtime PC users and are unfamilar with MACs so if we run into any technical difficulties it would be hard to fix. While I may be asking a biased audience (I was at the macfest united this summer in SF) i just wanted to get in as many second opinions as possible. Thank you, -William Sohn
