This might a bit a too early to ask, but do you already have any plans regarding Intel Haswell? In particular, do you plan to release an updated version of XPS 13 with Haswell under the hood or will come with a completely new laptop?

My XPS 12 has been having problems with the touchscreen -- as other have reported -- where it will suddenly stop responding to inputs until I restart the PC. It seems as though this is a driver issue.
