Recently did the same. I have two PC laptops, both less than 2 years old and one of them doesn't work. I bought the base 2011 MacBook Pro 13" in late March and have not touched a PC again.
And you are right about the AC adapters. The mag Safe on the Mac is awesome. Not to mention the battery life. I am getting 6-8 hours usage on my Mac. Last year I took the PC laptop on a vacation and while on the plane tried to watch a movie, I missed the last 10 minutes of it because the battery died. It was only a 2.5 hour flight and a 1 hour 45 minute movie.
