Except you didn't pay for a portable computer. You are technically savvy. You knew what you were buying. Now that you own it, you want something different.

Except you didn't pay for a portable computer. You are technically savvy. You knew what you were buying. Now that you own it, you want something different. I don't begrudge you deciding you want something different, I just don't think it is reasonable to imply that you were sold something different than you purchased.
