Panniers FTW.
If you request two laptops because you don't want to transport a laptop to/from the office then expect a lot of eye-rolling from your employer. Portability is the whole point of laptops.
I used to commute about 18-19 miles by bike with my laptop in a rucksack but moved to panniers when I got a new bike that could take them. I couldn't get on with them to be honest and went back to the rucksack. The cycling commute is less of an issue but my intention is to rotate bike and run (around 5-6 miles) which is more of an issue with a 2kg plus laptop in the rucksack. That said, I will hopefully drop more than 2kg off my gut when I start doing that regularly!
