Hi, As of December 25th, I'm the owner of a 20-inch iMac. To be honest - I love it! It's so much better than Windows, and I hope to stick with Apple for life. Anyways, after receiving my iMac, I seem to be using my three-year old laptop (Dell XPS M140) more; mostly because of it's convenience - being a laptop. My iMac was purchased off eBay around the beginning of December, so I'm trying to figure out if I should consider trading in my 20-inch iMac for a 13-inch MacBook. I'm guessing that I can't return it for store credit or anything like that, considering it was purchased in October and was re-purchased through eBay - unless of course I "accidentally" take advantage of the warranty by spilling coffee on it. Any suggestions or advice would be greatly appreciated!
