Based on a block consisting of about 28 seats, each seat being about 2ft, I think the screens look like being about 40ft wide. Mahoosive, woudn't mind 1 of the panels in the lounge.
Ive got a Tab & to be fair its not the best. Its a little frustrating & not very smooth. My wife has ipad and you cannot compare the 2. If you look on ebay there is a Brighton based company that sell ipads for about £270, if you can save for a bit longer. Hope this helps.
