Having had my imac for two and half years i can honestly say that i would not go back to the windows side of things , i have a 27 inch imac with 12 gb installed and a 1tb Seagate hard drive as a time machine back up , also using the ad block and bit defender traffic light from Safari extensions , the large screen is very good for building my website of Northern Ireland Photos and with the extra ram installed it is very quick in editing the photos using the Pixelmator software , lastly , although my imac is now out of warranty , three weeks ago when the problem of the ethernet connection arose , Apple care where on the ball with my phone call and all sorted out at no cost whatsoever , and thanks to this forum , i can keep up to date with all the news and info that i need for my imac use ,would i recommend imac to my friends ???YES
