When the Windows 10 upgrade delivers on July 29 I think it's fair to set expectations. Windows 10 will come with a bevy of new features and a polished UI, but will also come with compromise. What will release on July 29 is really just phase one and a base framework. Windows 10 will be supported through 2025 (10 years) and along the way Microsoft will deliver continuous updates to bring new features. What July 29 brings will be much different than what we can expect in 5 years.
However, as part of that base framework, slices of proposed features won't make the first go-round. One example is plug-in support for Microsoft Edge, the new, groundbreaking Internet browser in Windows 10. Another good example of this has surfaced recently.
According to a thread in the Windows Insider forums, the ability to install applications on SD cards has been delayed until a future release.
Bhavya Kashyap says this…
We have actually made the decision to postpone the apps on SD functionality to a later release. While I know this feature excited many of us, we didn't feel like it was ready for prime time. Our goal is to delight users with everything that we build, and we truly feel that that is what will happen once we have fully built our vision for this feature.
The discussion and response was predicated by a Windows Insider's inability on Build 10240 to install new apps to the SD card. For many, this will be an important issue, considering that Windows 10 will be available for lower-end devices such as tablets that are already low on storage space.
Bhavya has since clarified that the feature will still exist for Windows 10 Mobile which will be available for Windows smartphones and those devices with the mobile edition of Windows 10 installed. This compromise is only for Windows 10 PCs. However, this still poses a problem, considering Surface tablets run the PC edition of Windows 10.
