Due to mobility feature Laptop always scores over personal desktop, but still I expect longer battery back ups for Laptops.
PC has a lot of value, but I will go for a laptop because it is convenient. I can go internet any time
When I am at home I am generally on my laptop, but when away from home I am on my HTC Evo. I've been tryin to let people know, there isn't much this dang phone can't do. So let's add phone to that list too.
I don't think PC's don't have value anymore because personally I'd pick PC over laptops! Well,that's my personal opinion though!
I prefer PC over others because all heavy processing can be done on it and at least there is a fix place to work.
