The latest iPhone 5S rumour suggest that Apple may not be able to produce enough new iPhones to meet demand due to poor yield rates of the fingerprint sensor.

LCD driver chips are also in short supply, according to DigiTimes.

As a result of the slow production of the parts, the manufacturing has been put back to July, and as a result Apple may miss the scheduled September launch, according to DigiTimes sources.

If Apple meets the September launch date it is likely that the supply of the new iPhone 5S will be limited at launch.

According to the source, three million units of the initial shipments of iPhone 5S will be delayed to the fourth quarter.

This isn't the first time that claims have appeared suggesting that Apple's iPhone 5S (or iPhone 6) will be delayed due to the fingerprint scanner. Back in April, KGI Securities analyst Ming-Chi Kuo said that Apple's planned fingerprint sensor poses multiple technical challenges that could cause delays to upcoming devices.

"Apple has to work out how to prevent interference from the black and white coating material under the cover glass," he said. "Apple is the first to attempt this function and technology, and time is needed to find the right coating material, which will likely affect iPhone 5S shipments," he said.

Then in May reports claimed that Apple's new iPhone will feature what is referred to as a "sapphire crystal touch" home button. This new touch-sensitive button covered by scratch-resistant sapphire crystal glass will replace the current home button. The sensor needs to be scratch-resistant to maintain its fingerprint sensing capabilities.

That report highlights some of the difficulties in implementing the new fingerprint technology from the high cost of the glass to the difficulty of assembling the parts, and having to avoid scratching the surface.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
