Apart from the difference in usage commented above you do not worry about cannibalizing a market where you have less than 10% market share.
If you as an example could cannibalise the Laptop market by 100 units and you had 10% share of same you would only loose 10 unit sales in the first market and gain 100 units in the other market. In this case smart phones. Assume a 3 to 1 price ratio you would gain $2 for every 1$ you lost.
