Bought my first ever Apple (as long as the Apple II doesn't count when I was in 3rd grade) last night for the wife. After spending about an hour messing around with it setting up etc, I was very impressed. My first impression of externals of the MacBook were:
1. That it's SOLID. It's 5 lbs which unless your smaller than my 5ft 1in wife shouldn't be a problem.
2. I was amazed at how thin it was... I had previously owned an Alienware Sentia (supposedly the thinest laptop at the time '02).
3. I was exstatic about the magnetic power connector (my laptop died b/c the connector that you plug the power cord into came off the MB inside the case and shatter into a bunch of pieces)
4. The magnetic latch is pretty cool. Not anything really earth shattering but cool none the less.
5. The screen is awesome much better on the eyes out in the sun then a regular laptop screen. Yes this is the same one that so many people are complaining about not liking but haven't seen yet...
6. The keyboard. great design as far as not being able to get crud under the keys. I thought it was going to be a pain but the spacing feels exactly like a desktop keyboard... and the travel distance and firmness of the buttons are much better.
7. Integrated Graphics, again it's for the wife and she doesn't play 3d games so no worries. However I've played some 3d games on my laptop with the 855 chipset and it worked bearably. Bump up the RAM to 2GB if you're really concerned.
8. RAM, the 512 is fine for now for my wife.... I'm getting two sticks of 1GB simply b/c for the price to performance why not? You can get this type of Ram for about $80/stick. Well worth it especially if you want the graphics to have more memory available to use.
In Summary, it's a great machine. Well worth the price, not sure I'd pay the extra for the two upper models but that depends on need.
I spent 30mins today trying to figure out what antivirus software to get for a mac... does that show how long I've been in the windows environ
