Why this idea isn't "right" to me.
My plan is to get an android tablet. Data sync isn't an issue when the things I want are in the cloud. My same google account gets me my things on multiple devices already. All that would be needed to make it more seamless would be application/settings sync. I have no doubt with the dev community out there that this will be a reality once viable tablets are around.
There are a bunch of companies working right now on android tablets. Unless something has changed, even Cisco has hopped on. There are already generic 7 inch 1.6 tablets floating around $100. You would have to compete against this and the idea of phone compatibility. Even if you cover the flagship model from each carrier, you have a small intended audience.
The iIssue:
Apple has a cult following, we all know this. Not only will they pay a premium for products, many even pay $100/year for mobileme to get them what google sync does. I'm not familiar with the latest offerings so much...but I did use an ipad. It was quite smooth, and very polished. To the average user, it would be plenty. Argue it's downfalls all you want, the market for that device is there. I don't think you'd even get a second look from Apple users unless you had a name behind you.
Viable products in my mind:
-Android tablet
-HDMI/USB docks with inserts for different phones (yes...copying ipod)
-The docks above could be for alarm clocks, KVM setups, etc.
-Sync software so your account reconfigured the android device you are logged into for your settings. Think roaming profile in windows, but less data to transfer considering the cloud.
Valid points. I don't know if I'm the only one that wants only one device to "rule them all", but that's my vision.
Getting the EVO to interact with an external touchscreen/inputs could be the most influential advance anyone could make.
The "evo pad" idea could just be the beginning. There could be many applications for this kind of augmented docking system beyond replacing netbooks, MIDs, tablets, nettops, low-end notebooks, and low-end desktops. Another example would be car computer systems (carputers). They could become device-centric. Just a simple setup consisting of a touchscreen and an elegant media dock built in to a car's center console. The hardware would look no different than a current-day built-in car sat-nav system. A simple inexpensive phone upgrade would also upgrade most of your tech ecosystem. Everything from your "evo pad" to your car's media and nav systems could get a complete overhaul just by purchasing a new phone. In car wifi could be had just by triggering the EVO's hotspot feature when docked to your car. The need for the cloud could be leveraged or decreased by the simple fact that you carry around all of your data all the time on one core device. The cloud would just serve to deliver services, updates, and back up data on that one device.
The fear and negative impact of data capped plans could be reduced and the convenience of a phone's features could be amplified. Cost savings and feature benefits for consumers and businesses would be multiplied by just having one device for everything.
Maybe I should try pitching this idea as more of a "versa-dock" system instead of limiting it to just the "evo pad" instance.
I want smartphones to function as more of a digital "master key" for entire personal tech eco-systems. The "evo-pad" is just my first example.
There's no need for complex cloud-based syncing systems. Just have one device and make the experience dynamically scale to fit different environments (much like the car dock mode that exists on many present-day android devices).
All of this could be enjoyed with one simple phone/data plan. That means one reasonable bill for everything instead of buying a data plan for each and every device you own.
Example: A Sprint unlimited everything with premium data and hotspot plan ($140 per month) would give each and every person one connection to suit every single digital need and desire for all form factors anywhere they'd go 24/7 and only would require one $200 hardware upgrade every year or two and support up to 8 other devices to boot.
A "versa-dock" system that charges the core device would also greatly reduce battery life problems. Pull your EVO from the desktop dock on your desk at home in the morning with 100% charge. Plug it into your car dock as you drive to work, 100% charge again. Plug it into your "evo pad" while working, still 100%. Plug it into your car when driving back home, still 100%. You'll have a full battery when you pocket it right before you go out to have fun for the night.
Also, the more people that jump onto a single-device dynamic tech ecosystem, the less important tethering becomes. The monthly bill gets reduced and/or tethering becomes a no-cost added feature.
The only limiting factor would be a device's storage space. Right now, phones are limited to 32GB + internal storage space. This will increase over time and be augmented by external and/or cloud-based storage solutions.
Also, I know that I wouldn't get a second look from most people (not just Apple users) without a big name behind me, that's why I wrote in to HTC before "going public". I'm hoping that this idea gets some wings so that HTC (or some other large-name company) picks it up and makes it happen. The "evo pad" would be a rather inexpensive experiment for a large company and could open up the possibilities I've covered above... maybe even more.
Just some more food for thought.
