That's a good idea to hang on to your Voyage. Many have regretted trading theirs in. Also you can replace the battery on a Voyage and cannot on Oasis 2 and 3. I have an Oasis 2 and won't be trading up for the Oasis 3. I don't need the color changing lights so there isn't much point. I'll wait for the next revision. Whatever that may be. If my Oasis battery fails or something happens to it, then I'll probably get another Oasis 2 on sale. At least my covers will work.
