Yes laser do have a lifespan. I had to change mine in my Esoretic P2. It's been to the dealer since october and the laser is still back order (Grrrrr). but what I can tell you is that I bought the unit 5 years ago and was playing an average of 60 to 80 hours per week. Now all I want is to find maybe a P2s or to the dealer to tell me that i had received the laser and be happy like before...
