A few short years ago I had a Capital One personal card and a small business card. Total Mistake! Have I learned since then. They like to bait and switch on their promos and rip their customers off. Their rewards programs give you less and less over time. You cannot combine points/miles or top off frequent flyer accounts. Also Capital One subprime cards rarely ever give credit limit increases, and don't upgrade you out of their subprime interest rate credit cards. They don't report credits limits to the credit bureaus, which decreases your total available credit and may cause a lower credit score...The list goes on and on.

Don't Trust Capital One. No matter what the current gimick/promo is, Avoid Them and you've avoid potential problems.
