Can I buy a cheap laptop for around 150 USD taxfree at Taoyuan airport?

I need a simple laptop with good wifi, was wondering if they sell anything after check in at Taoyuan airport (if laptops are taxed high here in Taiwan)?

There are some laptop/tablet hybrids in that price range, but I’ve never seen that kind of product in a duty free area at an airport.

I’ve checked and never considered Taipei airport prices good enough to buy electronics unless an emergency.

Tokyo yes, sometimes.
