Mobility is awsome for a computer.
But i go PC cause its a quality product in alot more ways than laptops. PCs you can easily upgrade hardware, PCs last longer than Laptops, plus if you ever got a great PC game and need the graphics/Processing power to play a game i suggest PC period.
Anyways before buying a product. Get its model number and google it for problems. I bought a laptop with a default problem where the power jack wears over time and cost 120 cash in serives to replace it, which it only cost 5 dollars for the darn power jack, then if you wait to fix it, it would be 300 dollars to replace the mother board. Thats my experience with my own laptop, on the other hand i re-install windows every 6-18 months on my PC cause i download junk and it either A piles up over time or B a virus forces me to re-install. I got 2 different virus scanning programs, so if they cant find it well time to re-install windows lol.
Anyways happy hunting.
