I recently lost the power cable to my Mac Book Pro in Nairobi. There is no Apple Store, but I went out to Westlands - to the Sarit Center (right next to the Sankara Hotel) - and visited Elite Digital Solutions. This is an authorized Apple dealer. The store is well stocked, bright, cheerful and as close to an Apple store that you can get without actually being an Apple Store. The staff was helpful and knowledgeable. In fact, I bought the wrong power cable, and was able to bring it back and change it even though I no longer had the receipt. It's great to be able to rely on a store like this while in Kenya.
