No, you don't get it. It isn't the number of keys that makes it bad. It's the *quality* of the device itself. If you are a serious typist, a laptop keyboard will last you about a month, tops.
I live in an RV and we are a 2 laptop couple. The HP is 3 yrs old, my Dell XPS Gen 2 is 1 yr old. We both play very high graphics games a LOT..and I am a writer, type pretty fast. We also play online games, hammering out chat messages and using the arrow keys to move.
Yes I have replaced the Dell laptop keyboard after a year...but it cost only $17, it was delivered to me within 4 days and I had it installed in 15 minutes. This Dell is highly upgradeable.
Not so with the HP laptop, but the keyboard is tough.
A lot of people summarily dismiss laptops as viable desktop replacements. I wouldn't have anything else BUT a laptop. If I move into a house I will have a laptop.
The total portability of a laptop is important as I use Libraries while traveling to get Internet.
