I am planning to travel to India (Delhi airport) from the United States. I want to take my 2 laptops (1 personal and 1 professional) as well as my tablet (iPad). Am I allowed to take 3 gadgets in my backpack or in my check-in bag? I think I am allowed to take only 2 computers. Will Customs consider my iPad as a computer?
You are allowed to take as many electronic items in your backpack as you want through security, you just have to take them all out for the TSA check. The most important question is if you have to declare them and/or pay import taxes at customs.
As Ankur Banerjee states in his answer here on SE, you can bring one personal computer. so the second one will definitely be an issue. For the iPad, it's more difficult, because it's not defined, if it counts as a computer.
