PPI DIFFERENCE OF 40 ... is it considerable ....????

hi..

i am planning to buy tablet..... my budget is under 10k .... i am considering of buying above 7 inch tablet....


there are many limited options.....


i am cinsidering these following options

iball 6318i ---- screen 1200*600 (7") --ppi density - 169.55
iball 9018i ---- screen 1200*600 (9") --ppi density - 131.87


almost all the specifications are same...... i am very encouraged by the screen size.......

but 9018i has 40 ppi less because of screen size........


DOES THIS FACTOR IS GOOD ENOUGH FOR CONSIDERATION OF THE TABLET ???

OR IT DOESN'T MAKE A HUGE DIFFERENCE.....??


plz guide me in detail over it.....


thanks
