Tax-free weekend and my birthday right at the time of release will probably justify the hour drive to the nearest Microsoft store so I can look at the 8 G/128 G models. The statistical software that I teach and use runs only on Windows. On the weekends when we are at our camp, hauling a Windows computer so I can answer students' questions is a PITA. A 13" Toshiba ultraportable is too big, so I got a Surface Pro 3. Still too big, so I got a Surface 3. That's still too big. The Dell 8" tablet is a little too small and the storage is so small that I haven't been able to install the latest Win 10 update.
According to what I've read, the Go will be faster than both the SP3 and S3 that I have, and both of those are fast enough for what I need. I haul the S3 to class to run the statistical software and Office, but the Go is even smaller, which is fine with me. If the Go works, I may get rid of all four of the other Windows portables that I currently have, or maybe all but the SP 3 (for the larger screen).
I can afford it and will get one if I like it when I see and touch it. I have a very specific, uncommon use case, though, and I'm not as price-sensitive as most people. I've always preferred the lightest, smallest portables and am accustomed to paying dearly for it, back in the day.
Depending on what iPads are announced, I may be considering one (or two) of those as well, although I'm really happy with the iPP 10.5. If there's a new smaller one, I would certainly look at it as a replacement for my Mini 4. Am not interested in anything physically larger than the iPP 10.5 so a new Pro probably isn't as interesting, but that will depend on features. Unlike a lot of people, I'm not bothered by bezels or Home buttons.
