I used the stickers in the past and they sucked. It takes an hour if you want them put on properly and pressed flat as to not come up. After about two months the top gloss layer of the stickers come off and your keyboard ends up being sticky. Try explaining that to people. After about six months the printing rubs off and you have to replace the stickers so you have to order them and spend another hour applying them.
GET THIS KEYBOARD. It looks way better than any sticker will. The color keys sticks out more than the stickers do. It also has a nice professional smooth click when you press down on the keyboard and you will appreciate that if you do a lot of editing.
If you are using keyboard short cuts than this is a must! If you are not using keyboard short cuts than this keyboard is not necessary.
Also, the customer service for this product is great is the best I have ever experienced.
