if there was an ARM native version of the Office suite then I could see some value in this (as long as it's as usable and reliable as my trusty MacBook Air) but if my primary apps are going to be running in emulation mode it'll be a slow, frustrating experience and I suspect would never reach the expected battery life.
telcos will find ways to screw with the experience to try and drag an extra buck out of users (and the device will probably support limited bands which will make hopping countries a pain, not to mention international roaming rip-offs from folks like Telstra that have me searching for wifi when I'm overseas)
It does solve part of the the problem with the previous Windows Phones and ARM based devices in that it can finally run real apps so they won't launch with just the dozen than Microsoft Evangelists could pay people to develop (and drop as soon as the cheques stopped coming)... but the performance is going to be the make or break of this especially if they want to complete with an iPad for the same money but the added cachet of having well optimized apps created for the form factor...
Biting the hand that feeds IT
