Dell India promising shipment within 24 hours through Compuindia

The tweet was intentionally worded wrong. Included an asterisk:

Love the response these kind of tweets get on twitter.
They did put an asterisk but, I don't think they clarified it.

There are no Ubuntu laptops listed on that site. Did Dell stop selling them?

From what I understand Dell never launched Ubuntu based laptops in India.

I am not entirely surely but I recall that they were selling Ubuntu laptops at their outlet in Nehru Place.

hmm. i cannot recollect an official announcement. maybe local dealers were getting some units as a test to see the response from the market?

Anyhow. The reseller is probably stocking popular products. I think no customization options are available as well which you get when you order directly from Dell?

Dell's own website is not showing any Ubuntu laptop. If it's there it might be hidden in background.May be because Microsoft is going to or has bought some stake in Dell.

Dell.com/ubuntu would take you to their current offerings.
dell.co.in/ubuntu takes you to the same listings though.
