Advisor to spend some funds to buy things that make group members feel better working at home. Is it selfish to request a tablet and stuff? Due to the recent COVID-19 event, all of the members in our group have been working at home. My advisor proposed to get us some items to make us more productive or happy when working at home. I feel like a tablet would be very helpful in reading paper and books. Additionally, I'm working home using my small laptop and the screen is really small. It also helps if I could get a large screen to connect to my laptop. I have a bit of a quandary because those things are kind of not really necessary because, after all, I can use my laptop to read paper and work. On the other hand, they are not cheap. Would it be selfish for me to ask my advisor to fund me to get a monitor and tablet, those things?
Surely these are precisely the sorts of things that your advisor envisaged buying when they offered to get "items to make you more productive or happy working at home"? A decent monitor (and keyboard, and mouse) for your laptop are fairly essential if you're going to be using it all day every day for the next N months. A tablet is perhaps a bit more of a luxury, but hardly excessive. Remember, as a fraction of the total cost of supporting a PhD student, an iPad is small change.

If you're concerned, phrase your email making it clear that you are presenting a list of suggestions rather than demands, as you're not sure how much money the advisor will want to spend.
