HP looks like they are going to learn from mistakes and improve some things in the process. Some of the details on their Windows 8 tablet have leaked and this might just show some promise. They bombed on the HP Touchpad but if nothing else, they learned what 'not' to do in the world of tablet computing. I have always been a fan of WebOS and still think its a truly multitask-focused platform beyond how either iOS or Android handles it. The developer support just wasn't there for WebOS and Apple did, and continues to do, an incredible job luring and keeping devs developing on iOS. Developer support for Windows though? Different ball game than iOS.
If Microsoft gets Windows 8 right and the experience on a touch interface is practical and fun to use, then potentially all HP has to provide is good hardware and some marketing. If an HP slate was able to come into an enterprise Windows environment and be completely at home and immediately compatible, all while offering a user experience on par with iOS on an iPad, then there's a huge opportunity. The company I believe that has the best chance of denting the Apple machine is Microsoft - especially in the enterprise because of their presence in enterprise infrastructures globally.
HP's tablet will be geared towards business use, so chances of it having an ARM processor is probably slim because of the potential limitations on running legacy Windows apps. Here's an early look at what HP might have planned for later this year.
