(CNN) -- On this week's Tech Check podcast, Doug Gross, John Sutter and Stephanie Goldberg discuss announcements this week at the Mobile World Congress in Barcelona, Spain.
Among the phones featured were one with a whopping, 5.5-inch screen (the iPhone clocks in at about 3.5 inches), phones with touchscreen styluses (Palm Pilot, anyone?) and another that boasted a 41-megapixel camera.
And Microsoft rolled out Windows 8, a well-received operating system for tablets.
Are all these new gadgets cool, or uber-geeky? And will we ever actually see all of them come to market?
That's raised concerns from politicians and privacy advocates. But is it really a major change? We discuss the fact and the fiction.
Our Reader Comments of the Week come from Twitter, where readers responded to our story about a smartphone, also rolled out at the Mobile World Congress, that creators claim is waterproof.
And our Tech Fail of the Week goes to Google+ -- the social network that seems to see-saw from good news to bad news on the podcast all the time. This week, there was what we'll politely call a less-than-encouraging report about how much time users are spending on the would-be Facebook rival.
