I'm the one who dared mention I'm considering Dell (or HP). Just wanted to say my Dell Desktop is pushing 5 years old, never a single problem. (knock wood-that hard drive must be getting near the end......how long do those things last) It's just a home PC, lots of surfing and documents and photos, not heavy business use.
Still thinking. Leaning toward just waiting and see what news is out by 9/14......My brother (HUGE Mac fan) leans towards getting the newest one..
It does not take much on this furom to start a PC vs mac war

seriously dude (or dudette if your a girl). I'd go with a mac and run parallels or fusion so you can still have your windows stuff, if you need it. Some colleges require macs only. Other Windows only. And others do not care. Most will not let you hook into their network and if they do, then you must have a certain spec.
I run parallels, others claim fusion runs better (I got parallels for free pre-configured). I do not like boot camp as I hate rebooting just to switch OS's. If you are going to be doing something heavy like MS-SQL, video editing or something hardware intensive - then I would go with bootcamp so that you can have all your system resources dedicated to the one OS.
Seriously, get what you need and can afford. Just do your research first. I and a few other people on this forum have bought and then sold machines that turned out to be a way less than what they were hoping. a macbook is a good middle of the road (better than a mini, almost same class as an imac - but you are not tied to a desk, and less expensive and almost comperable to a macbook pro). I got my macbook with parallels XP, 2gb ram, 250 gb harddrive. I just got a wacom bamboo tablet to plug into the USB and turned on inkwell and handwritting recognition. So, now I have close to tablet features but less than the cost of a tablet PC (I heard Vista tablets are still a little glitchy - but I never tried one off hand).
me, I am satisfied. And if you do by a mac. Get Circus Ponies Notebook rather soon. It has comperable features as MS onenote, and automatic indexing features and if you buy before version 3.0 is released - you can upgrade to 3.0 for free.
3.0 I read has some nice features like native handwriting recognition, sketching, stickies, etc. Here is the link:

The only thing is some colleges are requiring MS onenote as part of the musts for a curriculum. OneNote runs fine in Parallels, fusion, and bootcamp. I also run it in parallels - I have not converted all my stuff to notebook or PDF yet. Just 2 draw backs on onenote:
1. Cache file will eat up your disk space.
2. Auto backups will eat your disk space.
you will need to watch those files and delete them occassionally.
One big advantage on OneNote is no Save button (yes totally weird for an MS app). It saves automatically, so if you lose power or your battery goes dead, you do not lose your work.
If you have any more questions click on my name and email me. I would share more, but I have to get up in less than 7 hrs for work (luckily I work from home now and tomorrows Friday - one of my slower days).
Oh and one more thing. Do yourself a favor and check out MACMALL.COM. they some some nice options and pretty competative pricing. They are an authorized re-seller and they will also have you applecare warrenty for you (applecare is a must - gives you 3 years with no worries and I heard from people have it also saved some of the possible repair hassles they would have had for the one or two flukey machines -opps may be starting another 100 posts). But seriously, get your applecare. MACMALL ships either same or next day, the system will be pre-configured, so all you have to do it just load any additional software you have. Pretty much I just took it out of the box, installed my extra software and was up and running in 15 min. Also, go to my blog on my website.
http://web.me.com/shervieux then click on blog and read "Tales of an Apple Switcher". Just one little note - the 2 button mouse thing. I turned on my finger click in my preferances (lay 2 fingers on the trackpad and click) - that is your right click. Or you can do what I did at first and justget a two button mouse. I come to like the two-finger click better.
