Microsoft dropped the price of the 32GB Surface RT to £279 from £400 in the UK, with the 64GB model's price down by the same amount to £359 (In the US, the cheapest Surface tablet went down to $349 from $499)
And in the US, Blackberry has cut the price of the Z10 phone to as low as $49 with a contract — down from $199 four months ago.
"It's a big deal for both companies," Tony Cripps, a telecoms analyst at Ovum, told the BBC. "Competing with the Apples and Samsungs of this world is tough, and it's a difficult climate to put out high-end products when the market is so dominated by a couple of players."
Recent figures from analysts IDC show that 49.2 million tablets shipped in January, February and March — and about 900,000 of those were Surfaces.
