Launching the Xperia Ray and active for different market segments is "a smart marketing move," Ramon Llamas, a senior research analyst at IDC, he stressed.
"There are tons of other Android devices out there highlighting applications and experience," Lama told TechNewsWorld.
"Sony Ericsson wants to push these devices such as Smartphones, but not just as a lifestyle and entertainment mobile devices," he said.
"How many Android sees now that are thin and run on Android 2.3?" asked Michael Morgan, a senior analyst with ABI Research.
"These days, that is just table stakes," Morgan told TechNewsWorld. "Now, Sony Ericsson differentiating itself with devices like active."
The new devices appear to indicate that Sony is taking a greater interest in his wing of smartphones.
"For a long time that it seemed as if Sony Ericsson was a bit of a red-headed stepchild," said ABI Morgan.
"Sony or Ericsson seemed to want to commit to it too. Now, I'm seeing more Japanese design influence, particularly active, which is a smartphone with a segmentation very specific, "he added
Smartphones in Japan are "extremely specialized," said Morgan. "Are solar devices, telephones, water, other types of phones," he elaborated.
However, the efforts of Sony Ericsson may be too little, too late.
"Our shows US Consumer Survey Sony Ericsson have a share of only about 1 percent of the US market," Dmitriy Molchanov, an analyst at the Yankee Group, told TechNewsWorld.
Still, 86 percent of 20 to 24 years old have a positive impression of the brand Sony Ericsson and both these phones, particularly active Xperia, target market, Molchanov said.
"Unfortunately, this is too little, too late" because both handsets lag other Android devices on the hardware side, Molard stressed.
"Nor has dual-core processors, and neither will support LTE," explained Molard.
Further, the Active Dock is offered with the Xperia "lacks the functionality of the Motorola (NYSE: MOT) Atrix smartphone offers" and needs more robust software, Molard suggested.
"Built-in sports apps and a water-resistant shell for active are nice, but they are not marketed and worse," Molard opined.
