I purposely never upgraded computers after 2000. Yes..I'm using the same five (almost six) year old machine since then with an incredible 733 mhz.
I've had plenty of opportunities to upgarde to something modern, but I know that doing so would put me in a big risk of f*cking up my social life and school career (once again) with all the games and sh!t...just like I did back in 2000 - 2001 during Counter-Strike and everything else.
If you don't play games, then wtf is the point of having a 3ghz computer anyway? All you really need are word processor/spreadsheet program, Internet connection, maybe an Internet messaging program, access to MP3s, and
a media player for watching porn. A 733mhz machine more than accomplishes these five tasks.
The extent of games I rarely play are checkers and spades and the sh!t that comes with Windows. They bore me so much I usually have to force myself to run them.
Also I don't play consoles anymore either. When someone offers me to come play Xbox or PS2 or whatever the f*ck I simply pass.
Do I miss it? Probably. But it does sh!tloads more harm than good for people like me with an addictive personality.
I really have no other choice during the day but to get the f*ck outside when I'm finished typing up my work and/or looking sh!t up online...and occasionally visiting the two forums I'm apart of and watching porn to get horny enough to want to f*ck something...because it gets boring as hell here.
You should definitely do the same if you're aware of this problem and allow it to affect other parts of your life.
