I was browsing laptops online and in stores this last week, and I noticed that most of "brand new" models are pretty slow. My current laptop is a Dell 5100 running at 2.66GHz with 512MB of RAM. I noticed a lot of the "newer" models are running at 1.something GHz or maybe a tad faster... Why the step backward? Feature wise they're lesser models compared to mine - which is almost 2 years old. what's up?!?
