Motorola’s chief executive has said that the company will come out with more versions of its Atrix smartphone cum laptop devices offering alternatives to PCs and tablets.

The Wi-Fi only model of Motorola’s Xoom computer tablet will be available in stores by the end of the month.

There were some concerns over the lack of Wi-Fi connectivity in the tablet initially but it has been addressed by the company with a dedicated Wi-Fi only model with more affordable carrier plans.
