I think why they have you use the store download is because they may plan for it to go to a regular price in the future, also by having it on your history by going through the checkout process, they can make sure you are notified of updates and such. Also if you have to get a history burn, Aiko will be included in that instead of you having to redownload it from the freebie area, or losing it when/if it goes to a pay for price. Now not saying this is DAZ's words, just my opinion and I know from my perspective I'd rather have it on my history :)
