The "hard shut down" is not hibernation, it's manually forcing the computer to turn off by holding the power button in until it shuts off (about 4 seconds); PCs have the same feature. The point was that sometimes things hang so bad that CTRL-ALT-DEL, or the Mac equivalent, just won't work, and you have to turn the computer off with the power button.
In the four or five months that I've had a MacBook Pro, I've had to force a shutdown several times, but all but one or two were because I didn't know how to force-close a full-screen program. So, I've really only absolutely had to do it maybe once.
Closing the lid to enter standby: This feature almost always works for Mac, only works about half the time for Windows XP installed as the BootCamp OS on the Mac. For Windows, it seems to depend on whether or not certain programs are running when I close the lid.
Compatibility: Not an issue. If the program you want/need isn't available for Mac, then install the Windows version you already have on the Windows you installed to BootCamp.
Alternative to BootCamp: Parallels or VMware. Either product runs in Mac and creates a virtual PC that you can install Windows on, then install Windows programs to the virtual PC. Run the virtual machine and you'll see Windows start up like you've turned on a Windows PC. You can run the virtual Windows PC in full screen, or windowed. Both programs have a mode that lets you bring running Windows programs out of the virtual PC's window and have them right next to Mac programs. So, on your screen, you'd see Mac programs running and looking like Mac programs in Mac windows, next to Windows programs running in windows that look like Windows windows. One of those two programs (think it's Parallels) even puts icons for Mac programs on your virtual Windows start menu. Because Macs use Intel CPUs and are basically custom PCs, these virtual Windows computers run little to no performance hit compared to if you ran them on a BootCamp Windows install.
Don't need to shut down, just put your Mac to sleep: Somewhat true. Sleep mode is NOT a power-free mode; battery power is still consumed, albeit at a much slower rate. You may get several hours from a Mac that was put in sleep mode when the battery was half drained, just don't expect to put it to sleep and come back days later and have it wake up. But shutting down normally and powering up normally seem to be a bit quicker for Mac than Windows.
The bottom line: Get the Mac. You seem to like its appearance better. Are you worried that if you don't like the Mac OS, you'll be stuck with a computer you don't like? Create a BootCamp partition, install Windows, and tell BootCamp (through a utility in the Windows Control Panel) to make Windows the default OS. Basically, you'll have turned your MacBook into a Windows PC.
Yeah, I knew hard shut down and hibernation are not related in anyway. I know what both are just not what one can do while a PC (or Mac) is hibernating because it's not a feature I've ever used.
My friend has Parallels and loves it, I assume with bootcamp it's one or the other OS at a time? You can't run them at the same time? Parallels is probably something I'd get eventually but I'd deal with Bootcamp for the first while.
I'm not only concerned about the learning curve but performance vs cost. I'd like if someone who knows something about both could look at the specs for both and let me know.
