[ereaders]

I am planning to buy an ereader within this week.
Looked at Kobo, Kindle and Sony.
I went to a retail store today and spoke with the Sales/Tech. He told me that nearly all of his customers used ereader would give him the same feedback.
"They only last for about a year. after the first year either the battery or the display performance will drop."
If this is true then I will buy the cheapest model that I can get in the market.
Buy another one once my first one die.
Do you agree?
