The rumored Apple's iWatch is apparently running into some "bumps", according to a new report from Jessica Lessin at The Information.

While there's not much information about it, it also sounds like routine bumps in the process of building a new product. Here's what Lessin is hearing:

• Apple has had trouble settling on a screen technology. It's having battery issues, so it's considered trying new screen tech.
• Apple "halted advanced prototyping of some unknown pieces with one manufacturer late last year" but she also notes that Apple shifts manufacturers all the time, so this might not mean anything.
• Bryan James, who was working on the iWatch, has gone to Nest. James worked on iPods, and has a patent for Apple with Nest founder Matt Rogers on a watch-like device. (Rogers used to be at Apple.)
