The new iOS 8 will land on selected Apple devices on Sept. 17.

The new operating system from Apple debuted at the Worldwide Developers Conference (WWDC) in June and is claimed to be the "perfected" version of iOS 7. The OS packs the same design but comes with new features.

Some of the software features included in the new iOS are updates to the photos, iMessage, and the keyboard applications. The search function, Spotlight, and iCloud have also been improved. iOS 8 also packs the much awaited Health application to help manage a user's health information, and it includes features like a heart monitor, BMI, and medications tracker.

The new OS will head to iPhone 4S, iPhone 5, iPhone 5C, iPhone 5S, iPad Mini, iPad Mini with Retina Display, iPad 2, iPad 3, iPad 4th gen, and iPad Air. While some users of the said devices may be excited to download the newest OS, it may be more prudent to wait a while.  

Below are the reasons why Apple fans should not rush in downloading and installing the new iOS 8 yet.

Bugs and issues

Although Apple released a number of beta versions of iOS 8 to comb out issues and rectify them, it is most likely that the new iOS will still have some bugs and problems.  Usually, these glitches are discovered in the first couple of weeks after release, and are resolved in the succeeding updates which often roll out a few days or weeks later.

Traffic jam

One of the usual woes on the first day of the iOS release date is the traffic jam in downloading. Usually, it will take a few minutes to download a new iOS update; however, with a large number of users updating at the same time, it may take hours downloading the software.

Some apps are not running in iOS 8 yet

The beta versions of the new iOS 8 allowed app developers to tweak their apps to be compatible with the new software. However, not all apps will immediately run smoothly with the new OS. Some developers are still updating to the make their apps compatible with the new OS.
