craving for a new netbook

Ever since E was born, I've stopped carrying my laptop on my trips, since it's just too much to carry on board the aircraft and I don't want to worry about it if I check it in. So, I've been thinking that a lightweight tablet netbooks is just what I need for when I travel, so I can just slip it into my purse and keep up with mails, photos and everything else online. It's a very tempting thought, don't you think! It's been almost three years since I bought my laptop and even though I still think of it as my new laptop, I always think it's good to replace them every 3-4 years. And, anyway the technology has changed so much since I got my last laptop too.
