For web-designing and general computing,
this Acer Aspire 3002 NLC would be enough considering it has a 15" XGA TFT LCD.
If u multi-task a lot while desiging loads of webpages, adding more RAM then the default 256 MB DDR RAM would be a good choice.
Considering your busget is 40k, you would get this laptop for 33.7k with carry case.
The other peripherals which you would have to purchase with it wod be a USB Mouse, Additional DDR RAM, and a bigger battery
All this would really be in ur budget
Personally owning this laptop, i m sure this wont disappoint you.
the best thing is the price, what else can u ask in a laptop for 33k?
Do check the link for more on that laptop..
This model is tough to find so availability would be an issue, i m sure this model wont last long in stocks
