Dell has always been my favourite.
Dell has got a wide variety of laptops there is a laptop for each and every diferent type of person. plus dell gives a really reliable international warranty.
I bought this laptop from somewhere in dubai but I am getting its warranty here in India, It is the best service that dell Gives. TAlking about Inpiron 1545, It is an amazing laptop 2, 7GHz processor 3Gb of Ram and 320Gb of hardisk. The Ram and processor makes it ultrafast and fluid. Plus the screen size is also good. All this makes it the perfect laptop for the students.
Only problem in this laptop is that its battery life reduce very early, and because of which I had to change my battery after 1 year.
But I really suggest students to buy this laptop(all software including designing software like caitia, autocad runs smooth).
