According to the Bloomberg report, the new devices will use Qualcomm's Snapdragon ARM chip—not the company's own Exynos ARM chips. While that may sound strange, Qualcomm revealed earlier this year that its chips were ready to work with Windows RT and already in production, which suggests Samsung was slow to respond to Microsoft's new offering.
If Samsung's existing tablet range is anything to go by, you could expect to see RT tablets in sizes suitable for everyone—right down to the nearest tenth of an inch.
More seriously, though, it's interesting to hear that Samsung might be planning to tackle Microsoft in the Windows RT arena, especially given that HP has gone so far as to announce that it will be shying away from the fight. Bloomberg reports that Samsung will aim to release its Windows RT tablets in October, the same month we expect Microsoft to start selling the Surface.
That would mean that Samsung will have some stiff compeition in the shape of the Surface—a device which promises a great deal. It will be interesting to see how Microsoft performs against seasoned hardware manufacturers. [Bloomberg]
