Jack Gold, an analyst at J. Gold Associates, said Microsoft should "abandon Surface RT and simply focus on Surface Pro and Windows 8 tablets, but make them less expensive and upgrade the features to be more competitive."
"With several companies now abandoning the RT platform, I see no momentum in the market to keep it going long term," Gold added.
Microsoft could choose to keep Surface RT alive indefinitely, but that would rob resources and funds from other projects that have a better chance at success, he added.
