Clearly for you, and a handful of other people, SD cards ARE the most ideal solution for multiple reasons like the unavailability of the cloud in the mountains, etc. I'm not saying people shouldn't want them, I'm saying Google has already moved forward with their plan to eliminate that tech from their platform and thus we should all be finding smarter ways to do business. Because of the limitations that both you and I have described, with SD cards (no apps to SD, failing cards, requires compromises in engineering, etc), external wireless drives (not sure why this wouldn't be available 24/7, but I'll take your word for it), etc. the most ideal solution can only be a combination of better access to cloud services and much greater improved internal storage.
I think as tech enthusiasts we think our paradigm applies to more people than it does. Most consumers do not know what an SD card is and many that do, would have no idea how that would relate to their phone, let alone how to swap them out, etc. Depending on data source, less than 2-5% of Android users root and we all know that most people don't troubleshoot things, they replace them. I do understand the appeal of SD cards to some people and I'm not saying that appeal is wrong; what I am saying is that the SD card train already left the station. All of the tech enthusiasts combined doing one thing to try to shape OEM development ... will accomplish little to nothing. We're by far a minority. I see comments on both sides of the SD card and removable battery argument all the time in comments of tech articles and in forums, but I've never heard someone who isn't sure how to uninstall an app mention SD cards at all. I'm sure, like me, you're constantly showing people things their phone can do that they had no idea about. That's where word of mouth campaigns come in. We can petition the manufacturers directly, but they won't listen. The only other choice is to get people excited about things and talking to their friends, etc. and using the only power we actually do have, the ability to vote with dollars.
I'm not trying to attack you and I've stated in here and in other threads where you go on about SD cards that I agree a more comprehensive solution should have been released first. What I'm trying to do is give information that helps readers bridge the gap between dying tech (SD cards) and their want to carry their entire music/photo/video library with them at all times. Some users have hundreds of gigs of stuff that they want to be on their phone and no 16GB device can touch it. I'm not saying that the existing solutions fit for everyone, I'm saying they help and that we should be pushing for better.
Aren't these devices beginning to blur the lines between phones and laptops....I want my mini laptop (cell phone) to have the option to expand storage. SD should not be a dying technology. Why would you acquiesce to this paradigm shift? Options are always good for consumers.
Everything does not deserve or warrant being stored in the cloud.
Stop making excuses and justifying what some big company is doing to make their pockets fatter - they are suppose to work for us - get away from the build and they wll come mentality. I guess thats the difference between a prosumer and a consumer.
Virtually every company submits to the demands of a big potential customer and they will go out their way to retain or obtain a big new client. Why aren't we demanding the same?
