On a slightly more serious note, any of the LED's will be infinitely better than a backlit screen for low viz and night diving. The Petrel 2 is easily read in daylight as well. Other features that may or may not compare or interest you is that it is Bluetooth so no cables needed but comes with an adaptor if your computer is not Bluetooth capable. The Petrel 2 has a recreational mode and a compass. I found it extremely easy to set up, especially for anyone with any experience with multi gas DC's.
On the down side, it is larger and a bit heavier than your current computer and I at least find the wrist straps secure but a bit difficult to manage. It can be threaded with bungees or even mounted to a slate if you prefer.
I looked at the A300 CS when it was first released and it is a beautiful and sleek DC and as I recall a little less bulky but at that time there just seemed to be a few too many issues with it and there was the planned Aeris/Oceanic merger. But it does offer AI, at an additional cost and its base price is higher than the Petrel 2
