I recently purchased a new Dell Inspiron E1705 machine. It's got a nice intel dual core processor, 1GB of fast RAM, a 60GBSATA hard drive, and most importantly a bright 17" screen. Fancy smancy.
At the time I was debating about getting a MacBook pro - basically the same set of specifications, but about $1000 more money.
One concern I had about the Dell was I heard that their support had gotten worse recently, so I purchased the extra 2 year support contract.
I really wanted a Mac - the OS features are great now that they've got BSD underneath it all and with Intel processors it seemed like it would be speedy yet battery friendly. Turns out that MacBook owners are not the happiest bunch of folks.
First, I read about how crappy apple support can be which is really sad. If it were the Dell he would have known that he was purchasing a specific level of support. My level of support - for something like $70 - got me 2 years of next day on site service. I have a problem, I call, I run through troubleshooting over the phone, if it's still busted (like his) someone is in my house the next day to fix it. None of this "sorry, genius bar is busy goofing off".
I've also read about heat problems on the MacBooks - those are pretty standard complaints about it at this point including this guys point that if you don't have a lap tray it will burn your nuts. Sweet.
Finally, today I got sent a link to this video of a MacBook Pro that refuses to come out of sleep. The best thing about that video - it's hosted on a mac.com homepage. Priceless.
For me, if I want an operating system that does everything but only works so-so while giving me a bash-shell, I'll just use these guides to get the support I need to have a busted sleep mode :)
