Yes. The netbook category started around 2007 and this was after USB is pretty prevalent on laptops - and many consumer laptops also came with SD cards. So the most likely answer is "yes" but you'll want to check the specs of the particular machine you are thinking about. If the machine doesn't have an SD card slot, you can also get there with a SD reader that plugs into USB.

I've used small laptops for a while on trips to upload photos and keep a blog. In 2007 prior to netbooks, I used a small sony (same idea but they charged a lot more for it). After netbooks arrived, I used some small HP netbooks including trip across Africa.

Two things I also do:
- I use it to upload photos, but I also make an extra copy of those photos on a removable media such as a USB drive.
- I also take with me key documents (e.g. passport, airline info, etc) scanned and kept on USB drive as well. I should probably encrypt that info too. I've also kept copies of documents such as the user manual to cycle computer in PDF format so can figure out how the settings work, etc.
