I build custom PCs on the side and have many years of knowledge and recommendations for notebook and desktop computers.
1. Notebooks
A: I only recommend Sager and Lenovo notebooks. You can check out configurations at XoticPC. These brands are not widely known but offer excellent quality builds, customer service, and warranties.
B: Dell has the worst customer service, HP are worthless as they break right after the warranty is up, Acer has good interior quality, but their keyboards, and form factors are weak and cheap as well as their sound.

esktops
A: Build your own. I understand most folks don't have the knowledge to do this, but it is not that hard. I would be willing to configure a system at no charge and help walk you through the hardware installation. I build my own PCs and save 1000's of dollars over retail for monster performance.
By not buying a retail brand name PC you can save hundreds and get better hardware for the same price as retail.
B: Do Not buy brand name PCs. This may sound strange, but most high end systems are built by individuals and no name companies offering superior quality at reasonable prices with excellent customer service and warranty service.
3:Apple Products
A:Apple makes Desktops and notebook computers for people who want a trendy , no fuss computers in many different formats. Apple is an easy way to navigate the computer world and hip.
B:Apple is extremely expensive. Apple products are very good, albeit very costly. Apple can emulate windows, but is not a gaming platform. Apple operating systems are easy to use, but limited as they are proprietary.
C:Apple computers give you less hardware for a lot more money.
4: Multi platform systems:
A: I have found PCs are much better at providing this capability. I run 3 operating systems on my PC. Windows 7 64bit, Linux, and Mac. This may sound a bit much granted, but as an enthusiast I look for many different ways to augment my experience. I am also an avid PC gamer.
So if you want a fully customized multiple use system, PC is the way to go.
Besides PCs cost less than Apple.
B:It is easier to upgrade a PC than an Apple computer. (More PC options)
