My employer is going to begin allowing us to use our own laptops at work. We use low-end PC's at work, and I hate spending 40+ hours a week on a system that sucks. So, I'm considering spending my own cash on a new MacBook Air, which I'll also enjoy outside of the office. My only hesitation is the wifi issues that got so much bad press not long ago. Do you think this issue has been resolved in the newer production lots, or are we waiting for a software update? Any input is welcome. Thanks!!
