What i was saying is,
If u need a laptop with very good specification like :

CPU
Intel® Core™2 Duo Processor T9400 (2.53GHz, 6MB L2, 1066MHz FSB)

Memory
4096MB PC6400 DDR2 800MHz SDRAM (2048MBx2)

LCD
14.1" Diagonal Widescreen WXGA display (1280x800)
Graphics Controller
or
13.3" WideScreen, TFT Display

HDD
250GB `SATA Hard Disk

Video Card
128 MB NVIDIA(R)

then it is expensive..

Acer Laptops wat u get for below QR 2000/- is with 1GB,
for vista to work properly u need atleast 2 GB.
Otherwise u need to load XP for better performance.
