Puuuhleeeze. I use my desktop as a gamer. Your Macbook/Macbook Pro will blow itself up trying to play games at 2560x1600 resolution. My desktop can. I have owned a desktop practically continuously since '93 and you will have to pry it from my cold dead hands before I give it up for a laptop permanently. In fact, the laptop I own as a second computer sits at home and acts a second desktop about 98% of the time. Not all of use are in need of constant mobility. I try to maximize the time away from computers so rarely take it with me.
And another thing - I dislike trackpads. Yes, Apple's is better than most but it's still nowhere near as good as a proper mouse especially in games. My laptop is a Thinkpad and I use the TrackPoint practically all of the time rather than trackpad.
First of all, that's great you love games, I love them too; more power to you
2) Your post doesn't really have anything to do with the topic. Yes desktop computers are more powerful however, the vast majority of consumers don't play games that require that kind of hardware. For some it is necessary, others it isn't. I personally play games on the console side because of a lower entry price and as a result, more exposure to other gamers and things of that nature.
3) I never said ALL of us need mobility. I for one will never get a desktop because the second I want to take my computer outside or sit with the girlfriend on the couch while relaxing I can't do that.
On top of that I'm in college so portability is a godsend for me. You dont' agree, that's fine, however critiquing my post because you feel differently isn't the way to share your opinion.
