I am much older but I consider Ivy Bridge and the iPhone 4S to be the best. So that's around 2012. I also think the 11 inch MacBook Air was the best laptop, but there is no equivalent nowadays because Apple wants you to buy an iPad+keyboard, which is actually heavier. The last year for that MacBook Air was 2015. Nothing has come out after 2012 that interests me at all, including the 'AI' stuff
