I'm afraid that creating a good seal for helium in a consumer electronics device is totally impractical. Helium atoms are tiny and non-charged, which means over time they will diffuse through almost any material, especially a flexible membrane. What might be interesting is if Apple set up a helium recharging station in the Apple Store where people can come in and just recharge the helium for free. The sales from increased foot traffic could easily pay for itself.
