Could buy 4 really nice Dell Desktops with 2200 ha. I personally hated using laptops until I got my ThinkPad. That keyboard has to be the best laptop keyboard ever.
I find more attempts made on the SFTP port than the RDP port. Nearly 1000 attempts a day on my SFTP server. (Port 22) Strong usernames and passwords are your best defense. Avoid using user names like admin or root or passwords like 1234. You'll be fine.
