Apple Inc. (NASDAQ:AAPL)’s new 4.7-inch iPhone 6 and 5.5-inch iPhone 6 Plus have spurred “the mother of all upgrades.” The new devices smashed all sales record in the first three days of launch. The iPhone 6 is beating Samsung’s Galaxy Note 4 even in South Korea. However, Apple co-founder Steve Wozniak believes that the big screen iPhone 6 arrived three years too late.

Big Screen iPhone 6 Came Three Years Too Late: Wozniak

iPhone 6 to be available in 115 countries by the year-end

Wozniak told CNNMoney that Apple should have built a bigger iPhone much sooner. Had the company launched a larger iPhone about three years ago, it could have captured a much bigger share of the global smartphone market. But the Cupertino company continued to make 4-inch iPhones even as phablets were growing in popularity. Demand for the new iPhone 6 is so strong worldwide that analysts expect the current upgrade cycle to continue through 2016.

According to the latest data from the research firm IDC, Samsung had 24% share in the smartphone market at the end of the third quarter. By comparison, Apple commands only 12% market share. At the end of October, the new iPhone 6 was available in 69 countries. Apple is expected to launch the device in 115 countries by the end of this year.

Wozniak isn’t excited about Apple Watch

Steve Wozniak left Apple in 1987, but he still loves the company he co-founded with Steve Jobs. Wozniak said he doesn’t exclusively use Apple products. He likes trying out gadgets before experimenting with them. Wozniak is not very excited about the Apple Watch, expected to hit the stores early next year. Apple co-founder was among the early smartwatch adopters. But he got “real negative on smartwatches” due to their small screens.

Priced at $349, Apple Watch will be available in two sizes and three collections. The one Apple offering Wozniak really loves is Siri. He purchased a stake in the company that made Siri even before Apple acquired it. Wozniak calls it the “best app ever.”

Apple shares fell 0.25% to $108.56 in early trading session Tuesday.
