I am pretty much done with the SBi5. Was working in excel and it crashed again. After system restart, my Outlook crashed. Chrome crashed 2x today. I love the device but am not productive with all the restarts and I go backward in productivity when I lose work. Reminds me of the early days when I was clicking save constantly. I'm wondering if the i7 would perform better. From scanning these forums, users with the i7 don't seem to have these issues. Any thoughts?
