What camera do you have?
Let's start with that first. And I believe it's "up to" 64 GB memory cards (which are so cheap these days anyway), You can use anything less too... infact as Far as I have heard about it... I didn't hear anything about what actual memory can be used. I think the Touchpad can just handle up to 64GB so most technicians are advising the highest capable memory a client can use.
Personally I have a lot of android phones and GoPros so I have a lot of micoSD - Nature of interest I guess.
but what @Gdkitty said earlier in the post..., it is technology. Not everything is compatible with everything. (iPhone example was good to relate as well).
Or you can relate it to the Windows 10 Upgrade. Even though Microsoft pushed it out to every Windows 7 and 8/8.1 users. Not everyone could get it based on their hardware. Even though it was Free!
But I get you, cost is a crucial point to make as well.
Why U bring hopes up? lol
So this infrared one is new?
I thought iCam2 was the infrared w/ motion sensor and that was the new one. (Which I just got recently)
There is a newer one that that?
Man! Technology never stops upgrading. ahhh.
