OK. place me on the "expansion" side of the arguement (and the stylus side, as well).
Of course, I was also the one to wait for a laptop with an e-sata external port and wanted it before it became "semi" mainstream.
In my profession, I have HUGE databases of information and the time saved per esata makes a great difference in effectivity. That is a particular case, I know others who use those ports for additional drives for movies, etc. Do most use it--probably not, is it useless, definitely not.
I have 30 GB of music sorted (yes, it's ALL legal) and regularly used. I enjoy the idea of taking movies on SD cards with me when I travel, etc. and having selection.
Sometimes what I want before I go on vacation is not what I want on a certain night (I'm picky, what can I say
).
For work I have large pdf files that eat up tons of space but I would like to read "on-the-go".
Then there is the huge questions of a) backup, b) privacy and separation and c) wireless connection. I want one device for several tasks.
I do not trust "cloud storage" as it is not mine and I have no control over it. I want my backups with me and able to be applied without using a second device or webprocess. I want to add and take away without erasing from my device permanently.
I don't want others gaining easier access to my libraries than need to be. I don't want to have to be "on grid" to get my information. I am not paranoid--I am private. And that is ok.
I have been burned by roaming costs before and do not want to have to factor that in my thought process. WLAN etc. is usually off on my devices unless I need it.
What I hear here are 2 sides: those who recognize general practical uses and those who personally have no use for them and deduct from that thought that no one else should, either. Give us miniSD just because it IS useful and those who don't need it can just not use it.
As far as I see, the SDcardless are not (much) cheaper than qualitatively equal products with SDcard slots.
