With Regards to laptops I was having to buy a new one every year just after the warranty expired, I had toshiba, HP, Sony & Ace and they all broke on the hinges and or the power connector within the laptop, they tended to overheat and I felt as if they had a self destruct countdown at 13 months old. Continuous Windows based issues both with laptop and PC and always having mouse issues......I just had bad luck.
3 years ago I purchased a new Retina Macbook.....My pictures seemed to come alive. They are built to last. I don't need any security software, SO reliable and a pleasure to use. Yes Apple products are expensive but I will never go back to a Windows based PC/laptop ever again. I also use a 5yr old iMac which I purchased used, again an absolute pleasure to use. They take a bit of getting use to but you will not regret the purchase. Updates I have set to take place at midnight and have not had any issues at all. I run Photoshop CS6, Photomatix Pro, Canon DPP, Lightroom, & recently downloaded all the free NIK Collection all work perfectly.
I was hesitant at first going over to Apple which is why I tried several brands before I made the jump. It was only because of the initial cost......I have demonstrated my apple products to friends and family not intentionally getting them to change but was surprised they did and they too love their Apples.
