Hi guys I'm searching for a external monitor for my Macs. It will be used for my older '08 Mac Mini and for my MBA. Keep in mind that I'm on a limited budget. I've pretty much narrowed my search down to these two Asus monitors both with IPS - 23" http://www.asus.com/Display/LCD_Monitors/VS239HR/ - 21.5" http://www.asus.com/Display/LCD_Monitors/VS229H/ The difference is about 50$. I'm not sure if I should go with the 23" and pay 50$ more than the 21.5". Is it worth it going with bigger? I don't game, but will be used for writing (a lot) and movies. I could afford paying the 23", but saving them wouldn't be all bad I've heard good things about Asus, and also Dell - but their prices is over my budget. Any thought?
