Glad you are sorted.
Yes, it probably would look even better if you had an Aura HD.
It's your choice, splash out on a HD, or wait a little while longer and see what is available nearer the end of this year. Kobo might come out with an improved Aura (not sure they will do anything more with the Aura HD, it was more of a limited edition due to the slightly larger screen) and Amazon will very likely come out with a newer, improved Paperwhite too. There is always something better on the horizon!
