Retina models do not come with a cd/dvd drive. I bought the superdrive (I have an iMac and MacBook so it does double duty). I have an exhaustive or excessive depending on your perspective, collection of CDs and DVDs. I have converted all the CDs but not the DVDs so it is a project in progress. Your needs might be very different. There is nothing stopping you from buying it later if you need it or buying another compatible drive that is likely a lot less expensive. 99% of your apps will be downloadable and almost none would come on a disk.
Most of the things you plan to do do not require a maxed out machine except the video editing, that can be RAM intensive and you might be better adding more RAM to 16GB. The RAM cannot be upgraded at a later date so if you need it, you have to order it that way. I am a photographer and I chose 16GB RAM so I could edit large photographs.
Flash storage is where you'll store your files. Basically the 512GB is twice the size of the 256GB drive. If you run out of space you can always use an external drive - but then you are carrying extra stuff. Video files can be quite large so bear that in mind when you make your choice. An HD movie can be 6GB or more so a large movie collection can fill up a drive very quickly.
I bought a BTO (built to order) as I wanted features I couldn't get otherwise. Refurbs are a great way to buy and it isn't unheard of to get more in the box than the specs say on the outside. Refurbs have the same warranty as new and many folks have posted how happy they are with refurbs. Certainly if what I needed was available as a refurb I would have ordered one.
Hopefully I have helped.

Stevi, thanks for your response, after hearing from the first two posters, I am considering upgrading to 16gn of ram. I'm looking at this model for $1,579.
2.4GHz Dual-core Intel Core i5, Turbo Boost up to 2.9GHz
16GB 1600MHz DDR3L SDRAM
256GB PCIe-based Flash Storage

That's a good model to buy new or refurbished! I bought mine new in October. My uses are pretty much just websurfing and Office though. The video editing you want to do may make 16gb of ram worth it for you. 256 vs 512 just means the hard drive space except that it's flash. Faster and no spinning disc to get damaged
I would recommend an external hard drive for backups if you don't have one already or using something like Dropbox. Even flash storage can fail and lose your data.
Good luck with the purchase!
Thanks KUguardgrl13, I actually use dropbox some now, do you have a preference for an external hard drive?

The SuperDrive (external DVD) is a good option, as is an external mouse (a lot of people have the Apple-branded mouse, but I went with the Logitech Ultrathin Touch Mouse - smaller, has a rechargeable batter with quick recharge time). Also, a lot of people get the Speck cases (or a similar brand) for their machines, although I haven't seen anyone using a screen protector on their MBP/rMBP. I've always had the clear case in the past, but I went with a blue one for this new rMBP for a change of pace. Even with a hard shell on the machine, you'll want a good bag if you plan to carry it around with you.
Thanks dmccloud, I have heard from several posters that the speck cases are popular so I will consider that case.

So what I'm hearing from most posters is to upgrade the ram to 16GB if I think I'll need it in the future. Here is my next question, I'm playing around for the different models and this is what I currently have for $1,579
2.4GHz Dual-core Intel Core i5, Turbo Boost up to 2.9GHz
16GB 1600MHz DDR3L SDRAM
256GB PCIe-based Flash Storage
Backlit Keyboard (English) & User's Guide

When I select the 512 GB model the only option is this which comes to $1,879.
2.6GHz Dual-core Intel Core i5, Turbo Boost up to 3.1GHz
16GB 1600MHz DDR3L SDRAM
512GB PCIe-based Flash Storage
Backlit Keyboard (English) & User's Guide
I guess my question is how much of a difference is the 2.6GHz compared to the 2.4GHz?
