The price changes come at a time when other vendors are distancing themselves from Windows RT. Lenovo has stopped selling the Yoga 11 through its website, Asus has said it was moving away from the development of RT tablets after the failure of its VivoTab RT. Microsoft dropped the price of its Surface RT tablet last month from $499 to $349.
Microsoft plans to announce the successor, Windows 8.1 RT, on Oct. 17. Dell has said it is committed to Windows RT, and the OS got another potential boost with reports on Friday that Nokia will release an RT tablet, though analysts called the idea "bizarre."
Dell will likely not abandon Windows RT because it has a close relationship with Microsoft, Kay said.
