The age old question: which one is better, mac or pc?
Personally, I prefer a pc due the need for Microsoft Office (Excel, Access, etc.). I know Mac’s can run Office, but it’s not the same. However, the Mac is full of awesome features, so I completely understand the Mac camp.
In terms of user friendliness, the Mac has its benefits.
Ultimately, you have to figure out your own needs and determine which platform works best for you. If you have an iphone or other Apple products, a Mac is going to be a better fit, due to syncing everything up.
If you want a productivity system, I recommend a PC.
