A Microsoft Surface Pro is in my future. But I hesitate for a couple reasons...... Logistically, this would be my first computer/laptop without an optical drive. Sure I could always obtain a USB connected optical drive, but do I really need one? It seems like most software can now be installed from the internet/cloud. And of course I have my "old" desktops and laptops that have optical drives. Will I miss having one if the Surface Pro becomes my main PC? Timing: Should I wait to purchase a Surface Pro 3 until it comes with Windows 10 installed? My current laptop has Windows 8.1 and I am not a big fan. Looking forward to updating everything to Windows 10. Yeah I know that the upgrade will be free, but I'd be happier purchasing a new unit with Windows 10 already installed...... And if I am going to wait for a Windows 10 Surface Pro, perhaps I should wait for the Surface Pro 4?
