By the way, if you're considering a Charge purchase, be aware that it's the first of three new Fitbit wristband activity trackers that offer smart notifications. With both Charge and Charge HR, which is expected in early 2015, you get caller ID notifications from your Android or iOS smartphone, along with the traditional Fitbit activity stats. For $20 more, Charge HR ($150) adds continuous heart-rate monitoring.
Fitbit Surge ($250), also expected in early 2015, will be a larger fitness smartwatch with GPS, music playback controls and smartphone notifications beyond caller ID.
If you're unsure whether or not you'll want the advanced features of Charge HR or Surge, or you're toying with the idea of an Apple Watch (also expected in early 2015, for $350 and up), don't rush out to buy Charge. Then again: Charge is a perfectly good product, a few months is a lifetime in the tech world, and you can always sell it later on eBay. So your decision, either way, isn't worth -- sorry, I have to say it -- losing sleep.
