user4669: I am working on a project that involves sending motion sensing data wirelessly from an arduino to computer. Sensor readings have to be transmitted continuously (say every mili second). I am not sure if Xbee is my bet. I came across this link
which suggest s that there should be atleast 10 ms delay between packets if you're using xbees. 
What are your experiences with xbees? I don't want to waste money. 

user7045: Xbee costs about 1000INR. They are really expensive. You should buy HC-05 module, which costs about 320INR.
You can easily interface them with Bluetooth of your Laptop using Processing Application.
You can even use ESP8266 ESP-01 Wireless Module. They Cost about 3$.
Wireless module gets connected with your router. this tutorial will help you to start. You can by this module from here.
nRF24l01+ modules can not be interfaced with Laptop...
