I don't think it makes much of a difference since Bitcoin has "satoshi" to represent the smallest decimal. Even if it attracts users, I'm pretty sure there are a lot of similar coins out there with 2, 1, or 0 decimal places, for example,
ecash. Some BTC wallet also have the option to display bits instead of the whole BTC.
Therefore, if you want to create token that can attract people, indivisibility or decimal places aren't something that you can sell/promote. It's not new, not interesting, thus you need something better than just numbering.
