Greetings, Navygirl, welcome to Apple!
Well, for one..I've always wanted a Mac, any Apple product really, but they're so expensive.
Actually, most people save money by buying Macs. There's an old saying "Penny-wise, Pound (dollar) foolish" which means people who compare items and buy the cheapest one save money in that purchase, but often find that the cheap thing breaks down fast, and have to buy the thing over and over again, losing more money in the long run then they saved. Macs save you money in a lot of ways.
First, they last longer than most other laptops. I still see "Clamshell" Macs in use which are eleven years old! If you buy a Mac Laptop, you can expect to use it for a good 4-5 years before you might feel the need to get another. So cut the cost in half because you're saving having to buy a new laptop in two years. Then consider that they retain their resale value. You can actually sell the old Pro and get some money for it toward a new one. So, you save money that way.
Next, you won't have to buy virus protection. So you save money that way, and you won't have to buy a lot of software that you often have to buy with PCs because Mac comes with almost all the software you need bundled in. That includes photo, video and music software. You can also run the PC programs you have on the Mac if you wish. So you have two-in-one computers. So, again, you've saved money. As you can see, if you were to add all these things together, you might well find that the Mac was a much better deal than even dirt cheap laptops, because dirt cheap laptops are no-frills laptops--they seem cheap, but after you've bought all the stuff you need for them, you've spent almost as much as you might have on a fully equipped Apple. And you get even more with the Apple then just the extras you'd have to buy if you went cheap.
As you said, you've got great customer support and 1 year warranty (unless you buy Apple care which gives you 3 years, and constant phone support). Again, you save money because problems will get fixed without incurring repair costs (obviously, if you spill coffee on the machine, all bets are off). There's also an element here of you-get-what-you-pay-for, which means that you'll get good quality screen, aluminum body, built-in camera, illuminated keyboard, sound system, long-life battery, even the plug which pops out if you pull it so you don't bring the computer crashing to the floor. So while the computer may be pricy, you are getting your money's worth.
And yes, the Macbook is very good for using daily. I recently had to remind a new Macbook user that she need never turn off the computer or quit programs. She only need close the lid and go. Open the lid and start up again. This is where you'll save the most money. You'll be more productive, get more done and that, again, saves you money. In short, by and large, Mac Laptops are good investments.
You don't have to get the most expensive machine, either. 2.23GHz is fine for you, as is 256MB. You will probably want 4-8GB RAM (memory) as that keeps things speedy and allows you to have a lot of programs running. Videos and music do take up room on a laptop and that should inform you as to how many MG of harddrive you might need. Better to have, as recommended, a back-up drive for finished videos. That will keep them from taking up room on the laptop. You may also be able to find refurbished pros and used pros at a discount if you still don't want to pay full price.
Does this help you with your decision?
