I wrestled with the choice between these two earlier this week. I liked the aesthetics of the T000E better. It's slightly smaller and also friendlier-looking to my eyes (less likely to cause concern from muggles?) The Tag has a Death Star vibe...
But after shipping to my location the Tag was actually cheaper and has a theoretical battery capacity advantage. I'll have the GPS turned off so the Tag's greater GPS suck won't be a factor. So I got the Tag. We will see.
