What do you mean not a convertible one? And how much is your budget? That's the big question for recommendations.
I mean that it actually needs to be a sperate unit which doesn't require a keyboard etc. If it is a laptop per say it needs to be able to disconnect and support touchscreen. I think people refer to them as slate tablets because of this.
Budget isn't a problem. I'm thinking about the samsung which is around $800 with pretty much same specs
