It's still irrelevant dude. You are comparing two utterly different things targeted for two different types of users.
When you see the world you need to see from average people's point of view, maybe you and I can afford a pair of Titans, but most people have their whole rig in that budget.
I am a gamer, I am a PC enthusiast, I do other simple tasks too, like browsing, watching movies which can't be watched with family on TV (
) and slight bit of video converting of my game-plays too. Now I do that on my rig, flawlessly, at 40-50% less budget than a laptop, without generating so much heat. So why on earth would I get a laptop? I seriously doubt how many people travel to every corner to their house and carry their laptop. When they do something they ultimately have to sit somewhere and do the works, and even a bloody lazy idiot like me is saying this! As someone said, you connect your laptop to an external display, you use a separate keyboard, mouse, so it's basically desktop materials you are using, it's the whole experience that matters, along with superior hardware of course. If you say laptop that'd mean that squared box only, nothing attached to it.
Desktops are better than laptop for any or every sort of work which doesn't require portability (for portability nowadays some sodding tablets can do the work of a laptop), let alone gaming / heavy rendering works, they are way more durable, consistent too, and I bet you know and believe that too, but you are just in a point of your life where for whatever reasons you can't have a desktop, well I get it. Back in 2006 when I used to sit back on my Fiat Palio and had no job and see some other person's 3 series going past me I just felt sad each time I saw those bloody cars, and kept saying to my mind, hey frak it, that has four wheels, this has four wheels too, what's the difference anyway.....but somewhere in my mind I had that urge.....and it's 2014, maybe some other kid now sees me and feels the same....but on those days I never (I was with a different username in TDF that time) believed or said anywhere that my car was more productive or better than that 320d even when mine was at least 6 times less priced.
I am confident that this will be my last post here.
