Names almost never matter
If the name for the new Amazon tablet ends up being “Kindle Fire”, the name won’t have an effect on the success or failure of the device.
Product and company names are almost always silly and weird. Doubly so for tech companies (Amazon, Google, etc.). As long as the name of the product isn’t offensive or hard to spell or pronounce you’re likely to be judged by the quality of the device, any marketing efforts you put into selling it, etc.
