Takes a little while to get used to the different operating system. Super reliable, very occasionally programs crash, but other than that never had the whole system lock up. System doesn’t slow down over time, my 2 year old mac still feels like new- I don’t ever feel the need to wipe it, or do any maintenance. Word for mac isn’t quiet as good, few little features missing.
Basically, if you can do it on a pc, you can do it on a mac, just slightly differently. Still use PC at work occasionally, its in no way terrible, but just different.
Reliability and build quality, customer service best things I would say. Learning curve initially the hardest part.
