Although cellular connections are much better now, Wi-Fi is still useful outside the home despite the naysayers.
There are at least a couple reasons for this: One, there are still dead or slow zones in some buildings when attempting to access the web via a cellular connection, whether it’s 3G/4G or what have you, (though sometimes the reverse is true also). Two, because the cellular providers are now imposing data caps on our already expensive and restrictive plans, many users, myself included, don’t want to chance exceeding the cap, therefore, prefer to use Wi-Fi whenever possible.
Until the data caps are lifted, long live WiFi!
