Wow I saw some of the presentation today and just naturally assumed there was also a segment on a new 'Surface 3' (non Pro). But you're right there wasn't one and a web search reveals nothing for 'Surface 3'. Very interesting. Are they just waiting to make a separate announcement about 'Surface 3' or are they indeed done? Time will tell.
It looks like Surface Pro is now larger, thinner, and probably closer to a PC laptop in functionality than ever before.
Can't wait to take a look at this thing at the local Microsoft Store. I doubt I'll buy one, but I think for many people this can serve as a good working hybrid between a tablet and a laptop.
