So it has only 1 XLR input, you barely have meters, no display, no control besides rec/stop, no secondary card slot to simultaneously record a backup on set, cloudservice has to be theirs with only 1 year included in the price, no pricing available for the cloudservice itself and no timecode. Sounds like a big fail to me.
But wasn't it the 5D mark II that started this whole DSLR revolution? That one wasn't announced until 17 September 2008, so in my opinion we're more than 2.5 years early for a celebration.
I kinda use this trick too, but not as explained here. I adjust while listening and looking at the multi spectral analyser. What I do is I fix the EQ of the dialogtracks first, which can be multiple adjustments in combination with a light compressor. I mix the dialog to make a good manually normalised track. EQ adjustments can differ between persons, rooms and microphones. While I edit the track I make mental notes of the frequency ranges I need to adjust later for the other tracks. I tend to use a larger Q for the EQ of the other other tracks. Then I listen on speakers, listen again on my laptopspeakers. If it sounds ok on both my audiomix is done and then I only adjust the main volume to make it -23 LUFS for R128.
