I think of lot of people will buy this at launch, particularly those receiving their end-of-financial-year bonus, but I won't be one of them.
I think it looks great, but it's too expensive, especially in terms of peripherals and games. Given its portable nature, I also wouldn't be surprised if a Switch XL or Switch Lite launches in a year or two.
Finances and quality of games permitting, this does interest me in a way that the Wii U simply never did, but it's not at the right price point.
Hopefully this will be the N64 launch where they dropped the price from £250 to £150 in pretty short measure when says started off sluggish. (At £280, it's a tough sell. At £180, it'd be a very-tempting offer.)
