I’ve liked the Mac laptops I’ve owned. Good machines, generally reliable and long-lasting. The Dells my friends have seem to often have problems and need replacement.
I agree with you about Dell. I won’t buy another one. But the Lenovo is a known quantity with me. They really are solid, I’ve been using them for years at work. My old T40 has 5 years of fairly regular airline travel on it, I only reboot it when I have to due to an install, the rest of the time it’s in standby in my bag or on it’s dock. Battery still has 2 hours of life in it and it’s 5 years old as well.
