Cant u extend ur budget by say some 10 K? Bcoz, for u 35 Ks u will definitely get a lappy, but u wont get a good enough one. buying a lappy with not many goodies attached will not make sense, but then budget is important as well.
For ur budget u shall get a Celeron based low-end system with around 256 MB RAM & a 40 GB HDD. Dont expect goodies like a Combo drive or a bigger HDD. Try looking for brands like Gigabit, Intex or Zenith...
If the system is just for basic home & office usage 35 K shud b good enuf. ...Else think of putting in some more moolah & a better configuration can be though of....
