Lightroom for iPad - how useful is it for serious hobbyists & Pros

Hello all

I am posting this question here as I could not find satisfactory answers by Google search.

I have two queries:

1) Is the now recently launched FREE Lightroom for iPad (you do not have
to have a Creative Cloud subscription - it is a standalone free of cost
software for iPad & Android tablets & so is for mobiles) as
functional as the original LR for iPad where one had to have a CC
subscription ? I have a perpetual license for LR 6.xx (not a cc
subscription and so was not eligible for LR for iPad before this Free
version came out) and I have now installed the free app from the Apple
Store on my iPad Air. Is this a scaled down version with lesser
functionality?

2) While LR for iPad seems convenient to do adjustments to photos taken with iPad, how does it really prove to be
useful for a serious hobbyist and for a pro who shoots RAW/NEF with DSLR
?

The idea behind LR for iPad seems to be to enable editing of RAW files on the go. But I do not see quite a few tools which are found
on the regular Desktop LR. From what I have understood one has to buy a
camera connector to iPad - which I have not yet bought - and the RAW
files are transferred to iPad as smart preview files for editing.

When only basic editing capabilities are present in LR for iPad (OR may be I
have not figured out where the more advanced editing tools are) how
does a serious hobbyist or a professional photographer has real
productivity with LR for iPad ?

And does one always have to have internet connection to transfer back & forth between iPad &
computer ? And are the files always stored in the Cloud?

That is quite a lot of questions from me.

Thanks in advance

Novelty IMO on iPad

IMO photo editing software on mobile devices is worthless 

Editing on tablets unless stylus is good is worthless and difficult.

I agree with everyone above, it would be rough. I don't know if iPads support mice / external card reader of some sort so maybe an Android is not as bad in this case since if you added all of that you are basically making a poor man's laptop??? Seems sort of pointless in the end.
