I had seen the S101. It is slim and has good looks but it will be expensive, it will cost more than Rs.29k.
It is much better to buy the Acer Aspire One with Linux and later install XP if necessary.
The inspiron mini has only SSD options till now. I am hoping that Dell would release a harddisk version when it comes to India. Then it will be great value for money.
The 80GB EEE PC 1000H is good value for money too.
