Thanks Harikumar.And to answer questions on the battery life, you'll have to charge it on a daily basis or nightly basis. Be sure you install battery saving applications like JuiceDefender to switch off any unnecessary usage of GPS, Wifi, 3G, etc. Carry your charger if you plan to use them frequently.
