Is this a worthwhile buy/sell? Quick Advice please??

I'm considering selling both of my laptops (a late 2010 Sony Vaio, which has Windows 7 and I like a lot and a 2008 HP which isn't that good but I could probably get $230 for) and buying a 2011 Macbook. I'd probably have to do this stuff over eBay, which I've never actually used. Would this be something I should look into?

Just considering it, my mom will probably not approve anyway, considering I have working laptops (one for my mom's and the older HP for my dad's house which just got a new screen). I know that I'd probably have to spend a few hundred more for the Macbook in the end, but I've always wanted one.

Thanks for any advice! ;P

Laptops or PCs running Windows usually don't resell for much these days when a brand new laptop which significantly better specs can be had for less than $500..

So even with the sale of your two laptops, you might have to bring a decent amount of cash to purchase the Macbook. Check out the refurbished store on Apple.com to see what the lowest price is going to be and figure out if you can swing it..
