Almost every person has a different opinion, so rather then telling you which to buy, i will tell you which not to buy. i think 90% can agree that sony viao, alienware, voodoo are a waste of money. Every other brand, people either swear buy them, or swear at them. Now, you need to be more specific on what exactly you want to do with it. A desktop has a waaay better price to performance. If mobility is what you want, obviously you want a laptop. If the laptop is going to be glued to your desk, and you just want it to "look cool", then be logical and go with a "cool" desktop. If you are gaming, go with a desktop. Now be more specific and we can recommend you actual models, brands. If you are video editing/graphics, some will recommend a mac. Although i personally don't like macs, it's all just a matter of opinion. And a desktop, 50 times to 1, will last you longer then a desktop.
