I agree completely with Jeff - if you've got a single product you're kinda fine, but if you're trying to train across the entire essbase\planning\HFM stack the (meaningless!) inconsistencies are a pain in the arse.
In many ways it seems like the oracle development guys are afraid of standardising to one particular method (imagine the outcry on this board if they went to the HFM formatting!) but...it's to the detriment of the entire product.
And the POV buttons are a travesty. The default is awful, the behaviour inconsistent, the drag and drop output is a nightmare (why would you include the top level dimension name as well in a list of 1!)
All that being said? I like Smartview. I really do. I just occasionally need to remind myself.
