You may not have thought much about the new phone in the works from Finnish device maker Jolla, but I spotted something in the design that struck me as interesting — particularly for those of us hoping to see how the best cheap phones evolve. Among the features listed for this Jolla phone are a back cover you can swap out for one with different colors and, more importantly, a user-replaceable battery.
That wasn't all that uncommon among cell phones back in the day, when handsets came with batteries that you could easily remove yourself. However, modern smartphones have opted to seal the device completely, making it impossible for the average user to actually access any of the hardware.
