But the super-weird keyboard means typing (like replying to texts and e-mails) takes a ton of getting used to... and the narrowness means you can't really browse the web. Even reading a basic news article becomes frustrating with only three words to a line. (Or five lines to a screen in landscape mode.)
And given that most people spend way more time texting and reading the news on their phone than making calls... it's crazy to me they ever had user research indicating this ever had a chance of succeeding in the first place.
