Hi,
I am new to Arduino. I am looking to create a data logger for our solar heating with 5 or 6 thermistor inputs.  I want to capture values every minute and send data to my Macbook.  However I don't want to leave the laptop connected to the Arduino board (a Leonardo) all the time with the serial cable and there is no wired ethernet close to the service cupboard where the Arduino needs to sit. 

So I am thinking of using either WiFi or bluetooth to connect with the laptop.  Does anyone have view on which is easiest and/or cheapest for a relative novice?  I envisage storing the logged values on the Arduino (for say up to a day) with a process periodically running on the laptop to upload the latest data.  I guess I might need an SD card on the Arduino to hold sufficient data - which leads me to think of a 3rd alternative which would be to periodically (say once a week) move the SD card to the laptop to manually move the data.

I would be grateful for any suggestions. 

Thankyou.
