...surely it will become reasonable (from a technical point of view) to port Second Life to them.
Check this out: "The ZTE Apache could beat Samsung's Galaxy S4 to the title of first
eight-core smartphone, according to a report. According to China Times,
ZTE is collaborating with MediaTek to release a flagship, octo-core
device." Specs for the Samsung Galaxy Note 3 are leaking; supposedly it will have three gigabytes of RAM to go with its eight-core processor.
Combine that with the move to [icky portmanteau word alert!] "phablets", smartphones with displays of sizes approaching those of (small) tablets, and you have a device that one would think could run Second Life, if the effort is put into porting it.
I wonder whether anyone will try?
