Hi Paul, here's my 2 cents on your question:
1) How SI makes their products shine on Mobile
There is a mobile template (not a mobile app) from SI you can read about and purchase
here.
As you know, more and more of our users are on mobile. That's why site owners/admins would love to have our site accessible on mobile. We'd also like to be able to use the various native features on a mobile device to best engage, support, reach, and delight members of our site as well. I believe SI knows that and has done so much toward making all of their components sing on mobile. From the SI app store where they sell their mobile template (it's just like a Joomla template you'd apply to your site, but it's a plugin, it's not an app):
Renders your site beautifully on mobile devices with this template. Developing native mobile apps are getting costly and it's going to take a lot of time maintaining a native web app.
Having a mobile layout would enhance the user experience when visitors visits your site on their mobile devices.
This mobile template works with all SI products. I have a license and recommend it to everyone who uses SI products and desire the best mobile experience for their users.
SI also has another plugin I have licensed and recommend called
Docker which you can read about and purchase
here. In summary, it offers system alerts, improved page load, and menu navigation for mobile, again SI is always seeking to delight mobile users.
2) How can a site owner/admin demonstrate/see the difference of SI products on a mobile device/tablet vs a laptop/pc?
Well, soon SI will post in this thread when their ES demo (actually will work for all their products), viewed from a browser on your mobile phone allows you to select the "mobile template" icon. This switches to the mobile template.
Hopefully they will add an option to show docker as well. This will show you exactly what the mobile template plugin and Docker alone or together can do to make the mobile experience stellar for your site members.
To see the difference without using it, simply turn off the mobile template when browsing the demo on your mobile phone. The difference will be clear.
I'll be posting one or more actual live demo apps as well, and you could look at those while looking at the SI demo from your laptop. Either way works, but you'll see more native mobile features demonstrated alongside SI products in what I post because it's actually a mobile app vs just a website on mobile. You may not need that, which kinds goes to my answer to your question below (hope I understood your question correctly):
3) What's the difference between EB vs ES vs ED etc. each product is intended to meet a particular user scenerio / user need for sharing, reading, searching, modifying, or communicating information. Whether to use one or the other depends on the user scenario and what need you're trying to fill, what problem you're trying to solve. If you tell me what that particular need is, I could share why/how a particular SI component is a good or bad fit. Sometimes no SI product fits that need. Sometimes it's one, or a mix of them. You have to know your customers well and SI products as well too. I remember the saying, just because you have a hammer doesn't mean every problem is a nail
4) Mobile Apps
Now, you don't need a mobile app in order to see your site on a mobile device. And SI has the mobile template and docker to make this an awesome experience. That's all so many users need. Plus, you can make a bookmark to your site, use the mobile template and docker, and walla, you have your site on mobile!!!
But, for some user communities this isn't enough. Many users are so familiar with the App Store or Google Play, they actually want to download an app from there.
Also, we now have push notifications to the web browser, but that might not be sufficient for some who want to push messages to the mobile device, the lock screen.
Moreover, there are native capabilities on the phone that can be leveraged alongide a social community (or any SI product used in your site) to maximize the value-add for your end-users, make a delightful end-user experience, differentiate your site from others, better fit in with the traditional world so many of our non-programmer site members live, which is the world of mobile apps.
Just one of an almost unlimited examples let me share that I use the membership card solution I've created and referred to above (it'll be an add-on for those who'd like it, maybe bundled in but price sensitive --- anyway, they're stored in the mobile wallet on iphone/android) but also the Events Booking component from a different vendor: JoomDonation. Both of those can generate a QR code to meet various workflow needs of the feature so the user scenarios can be met. Including a QR reader in your mobile app that also supports SI products means you don't have to worry "does the mobile user have a QR scanner installed" --- because you wanted it there, you put it there, or we did for you when we helped design/build your app! You wouldn't believe how long I've been waiting for a QR reader in a Joomla product that could be flexibly used for my customers needs like this, and not as a Porsche-priced custom development job or single-purposed task. I've investigated more than one Joomla vendor to market test what's available, at what price-point, for what closed vs open use so I have a fairly good knowledge on this
So to sum it up: I love SI products! But I also needed a working mobile platform for my Joomla web plans because I know my users are on mobile and I'm a dinsosaur if I'm not there alongside my site as well. That's why I invested so much time and resource using the solution I have and based on my experience investigating other altnernatives, I know this is amazing and will really change things up.
It's not just for ES, it's for all SI products.
