iPhone 6 global launch kicks off with a bang

Apple (AAPL) enthusiasts around the world proved their unflinching loyalty yet again during the global launch of the iPhone 6 on Friday.

In Singapore, one of ten countries in the first wave of the global launch, queues began forming on Thursday afternoon and telco launch parties kicked off at the crack of dawn.

20-year-old student Gordon Xu, who parked himself outside the Apple store at Paragon Mall on Orchard Road - the city's main shopping street - at 12pm the day before the launch, told CNBC he isn't taking any chances. The iPhone 6 Plus will raise his total count of Apple products to 6.

The 4.7-inch iPhone 6 and 5.5-inch iPhone 6 Plus have met zealous enthusiasm, reflecting consumers' growing preference for large-screened devices. International Data Corporation predicts shipments of phablets - smartphones with screen sizes from 5.5 to less than 7 inches - will reach 175 million units worldwide in 2014, passing the 170 million portable PCs expected to ship during the same period.

For some consumers, however, it's not about the new specifications.

27-year-old Kristy Wu, who was first in line at telco M1 (Singapore Exchange: MONE-SG)'s flagship store where music was blasting to pump up the crowd, said "no matter what, I was going to get the phone even if there were no improvements."

"I didn't read the specs or anything because I'm Apple supporter," she told CNBC.

In the first 24 hours of pre-ordering, Apple iPhone 6 and iPhone 6 Plus orders hit a record 4 million. That compares with 2 million for the iPhone 5, according to Apple.

Singtel, Southeast Asia's largest telecommunications operator, said 15,000 slots for the new iPhones were snapped up in less than 15 minutes when it opened its pre-order page to customers.

Some analysts believe with the launch of the iPhone 6, Apple is poised to begin another "super cycle."

"We believe Apple is in the midst of another 'super cycle' that begins with the rapidly growing 'phablet' market via the iPhone 6 Plus and extends into the wearable category in early 2015 with Apple Watch," said Brian White, managing director and global head of technology hardware, software and equity research at Cantor Fitzgerald.

Before this happens, Apple will need to address a critical shortcoming: its inability to meet consumers' demand.

Last week, the company warned that demand for new iPhones exceeds the initial pre-order supply. While a significant number of devices will be delivered to customers beginning on Friday and throughout September, many iPhone pre-orders are scheduled to be delivered in October.

Technology analysts partly attribute the supply constraints to the supply chain, which began ramping up production for this iPhone launch later than in the past. The iPhone 6 Plus faces more severe supply constraints than the iPhone 6, they say.

A representative from Singtel confirmed that the iPhone 6 plus is in high demand and stocks are running out quickly.
