The story, if anyone is interested.... we were on a 2 week pilgrimage trip to israel where i was begging my mother to buy me a laptop, then we stopped by dubai on the last day. i wanted badly a laptop so i picked this and checked if it had errors. limited choices was there, then again as i said, i wanted a laptop so bad. Now, i feel so disappointed and depressed that i made a wrong choice or did i not? i always wanted a laptop where i can play new games at.... now, i cant even make my sister happy by letting her play sims 2.... i feel like cryng that i rushed this.... i hope someone can help me.... im so damn stupid... i should have waited and researched..
