NPD’s latest figures show that HP is leading the US tablet market for 2011, unbelievable as that may seem… A quick guess would have said that Samsung is the ruler of the US market, when it comes to non-iPad slates, but things are not like that. The study done by NPD Group details the sales for the first 10 months of the year.

With a mere 1.2 million slates sold at retail across the country, aside from Apple products, the rest of the companies don’t have much to share between then. HP leads the pack with 204k units sold between the launch time and October. This means that the fire sale and the $99 TouchPad were actually a good move, making HP a leader in sales.

Samsung is very, very close at 192k units and they stand to face embarrassment here, since they’re performing wore than an injured giant and dying OS. However, one must take into account the entire war that Apple waged against Samsung and its latest Honeycomb tablets, trying to get them off the market. Meanwhile, globally Samsung hasn’t detailed the shipments of its tablets, after screaming out loud that the Galaxy Tab was a success back in the days.

Other interesting mentions in the top US tablets are the ASUS Eee Pad Transformer with 10% and 120k units in 2011, then Acer Iconia Tab with Android and Windows and finally the Motorola Xoom with 108k units.
