This type of application is where I find some of the new tablet/laptop hybrids interesting. They suffer from similar fixed configuration and limited physical connectivity issues as tablets, but otherwise seem to offer decent laptop performance in a tablet package. I just got a Surface Pro and am running full AutoCAD 2014 on it, with an 1.7GHz i5 processor and 4GB of RAM should be able to handle most audio design and analysis programs.
And yes, it is running Windows 8 Pro which may be an issue in some cases but it allows some programs to run in XP emulation and I have been pleased with how user bases have worked out getting some software to run in Windows 8. Many software developers seem to not want to invest in addressing compatibility for older software versions if they can instead try to sell you a new version, but in some cases the user bases seem to have worked it out themselves and are willing to share that information. Drivers are another issue, but those seem to be catching up for most recent hardware devices. I am looking forward to Windows 8.1 and some, albeit modified, return of the Start button.
I'm also becoming a fan of the subscription approach to software that has routine version updates. Having AutoCAD as a subscription will let me run the latest versions and avoid compatibility issues with clients and software for several years for less than it would have cost to purchase the upgrade that would otherwise have been required just for the Windows 8 compatible version.
