Actually, it has gotten even better than that!
We've been waiting patiently for Mugen Power to supply us our allotment of the X50 batteries and we have been advised that we sould be getting them within the next couple of weeks. We are anxious like everyone and as soon as they are available we will let everyone know about it. That is why we've now listed them in our web store.
However, in the meantime, we have also placed our orders for Dell branded OEM batteries for the X50 and the X30. They are now on our web store and will be available in about a week.
If you are unable to wait for Mugen Power's version and/or prefer to buy OEM batteries, we will now be able to offer this to you. Please visit our web site and take a look at the new products.
