Why can't I find any laptop with u300 or any processor from this lineup as it is a sweet spot between cheap celeron and a bit priced i3, giving affordable and adequate power for daily tasks. fyi, I am from India and I can't find any laptop of this processor in India.

I've already selected the U300, as the processor isn't the sole deciding factor when purchasing a laptop. Despite the slightly better benchmark score for the Core i3, it doesn't concern me. I anticipated the U300 to be around a Celeron 4500 level, possibly a bit better, but it's on par with the i3, so all is well. It's a solid choice for a 14" laptop currently running Linux.
