BBC News - Microsoft and HP show off 'slate' PC
Reaction to the as yet unnamed device was somewhat subdued.
"What we saw confirmed my worst suspicions that this is your standard Microsoft software in a slate form," Paul Miller, senior associate editor of technology website Engadget, told BBC News.
"It's an interesting product in itself but Microsoft could have gone further. It's not anything new in terms of software and that is what you really need to make a device like this make people want to buy it."
However, technology blogger Devin Connors of Tom's Hardware did not agree.
"It looked really good given the short amount of time we saw it for and it has Windows 7. Everyone loves Windows 7 and putting it in a device the size of an e-reader is probably going to be a winning combination."
The lack of enthusiasm for the product was in part due to speculation about what - if anything - Apple may launch.
Rumours of a Apple slate - dubbed the iSlate - has dominated the blogosphere in recent weeks, although there has been no formal announcement by the Cupertino-based company.
"Apple tends to change the game and this Microsoft/HP tablet didn't blow them out of the water," said Dean Takahashi of tech blog VentureBeat.com.
Myself, I love my Windows 7 Touch computer, and I will probably be getting an iSlate later this year. In this area its simple, Apple though expensive creates new gadgets better than anyone else. In 4 years a Windows or Google Slate will take Apples place.
