Smartphones. Battery life is key. You won’t think the phone is so smart if it dies during a conversation. Go to www.cnet.com for reviews on the “talk-time” battery life of different models.
HD Televisions. Bigger is not always better because you want to buy the right size for your room. Use the television size calculator at www.televisiontutor.com to suggest minimum and maximum size for watching comfortably. You also can learn the difference between plasma and LCD technologies.
