Ok. Now let me remind you that with any of those computers you listed (the non Macs) you have to add a bunch of software to get the same functionality that you get with a Mac WITH iLife and OS X... Software is more than worth the difference, specially when you can start to use your Mac right away instead of spending maybe days removing all the crapware that comes with PCs these days...
Just a point of reference:
My old Dell Laptop:
1. 4 hrs calling support to go over the shipped computer specs with what I had ordered. Dang they keep you on hold for a long time and transfer you often. not to mention the guy was in india and did not speak english and onlty had a script in front of him and could not answer questions (just kept re-reading the same script)
2. 2 hrs making backups disks (mine was not shipped with any recovery disks and they wanted to charge me for them - most PC's you don't get disks and have to make your own backups; you are only given one chance on the first boot up only).
3. 1-2 hrs formating the hard drive to get rid of the restore partition, and crapware/trials so that I could have full use of my drive.
4. 1-2 hrs to restore the computer back.
4. 1/2 day to 1 full day switching over and installing my software and moving my data.
<hours for issues afterwards not included, this also includes downtime to reformat the hard drive once it became too fragmented and various other downtimes>
My macbook:
1. 15 min - take out of box, boot up and look around.
2. 1 hr to install software I purchased separately, and my old Windows software onto the parallels VM.
3. 2-3 hrs to move my data (I have gigbytes of books, movies, music, photos, etc - 100 gb worth and growing).
<had not had any issues in the 7 months I have been using it, so no downtime or hours considered>
When I buy my new mac (some point down the road):
1. 15 min - take out of box, boot up and look around.
Since I am using timemachine and an external drive, I know I can just drag my data from the drive to the new mac (I've done it before and also done it from this drive to another non-mac computer when I needed to move something) - not sure if applications in the applications folder would work correctly, probably better off re-installing as I will probably buy the newer versions anyway.
<time listed for draging data from timemachine backup to mac, not even a consideration. I would just start it up before bed and everything will be done in the morning>
<time for backing up new computer - not a consideration, I will just turn on time machine and let it backup while I am working>
Yes - I have spent more time getting a non-mac to the point of where I want it to use on an everyday bases, than I did with a mac.
Yes - thanks to ilife and other minimal apps a mac comes with (cleanly installed and non-trial versions), I have been able to ditch 1/2 to 3/4 of the software I owned.
