It's probably not that much lighter but that isn't where the weight saving is. It's the massive data storage racks on the aircraft containing all the content, notice the heavy metal IFE boxed in the middle of each row through the cabin, not to mention the enormous amount of cabling through the whole aircraft to sync the system when required (for safety videos etc).
See the following article regarding Scoot (an LCC I know but it makes no difference...) and how taking out IFE for ipads saved two tonnes per plane. Imagine the difference that makes to fuel use year after year.

Scoot Pte is offering Apple iPads to budget long-haul travelers after ripping out aircraft entertainment systems weighing more than two tons to save fuel.
The tablets helped the carrier cut 7 percent off the weight of planes obtained from parent Singapore Airlines even after a 40 percent increase in seating, Chief Executive Officer Campbell Wilson said. The savings will help Scoot, which makes its maiden flight today, cope with fuel prices that have jumped about 36 percent in two years.
Fuel is “the number one worry” for any airline, as it usually accounts for at least 40 percent of costs, Wilson said in a June 1 interview in Singapore. Scoot will charge economy passengers S$22 ($17) a trip to rent the tablets, which are loaded with movies, music, games and television shows.
Cutting costs and finding new sources of revenue will be key for Singapore-based Scoot as it seeks to make a profit flying older planes than other low-cost carriers and selling tickets as cheap as S$158 one-way to Sydney, a flight of more than seven hours. Singapore Air formed Scoot after budget operators led by Jetstar and AirAsia Bhd. won 26 percent of the city’s air-travel market.
The iPads are “a very smart move,” said Corrine Png, JPMorgan Chase & Co.’s Singapore-based head of regional transportation research. “If they can make the aircraft lighter, it does help improve fuel efficiency.”
