Hey, DellGirl, glad to hear you're considering purchasing Lenovo. Here's a link to a pdf that details the 1-year limited warranty (https://download.lenovo.com/pccbbs/thinkcentre_pdf/l505-0010-03_en_update.pdf) that comes with the Yoga Pro 9i. Dates may vary, but your 1 year of coverage will start at the date of purchase at the latest.

Hi, Chad, yes, it does. It features an FHD 1080p camera with a Privacy Shutter.

Hi there, yes, you can use a wired, wireless or Bluetooth mouse.

Hey, Tam, depending on if you need any special software for nursing school or if you consider yourself to be an above average multi-tasker with multiple tabs and windows open, this Flex 5i could be a good fit for you. It's a 2-in-1 with pen support to make it easy to take notes, smaller and lightweight to make it more convenient to travel with and has solid specs for tasks like web browsing and streaming. If you want a more premium device with an aluminum build, higher performance thanks to faster memory and its processor and a higher tier display, consider the Yoga 7 devices (https://www.bestbuy.com/site/lenovo-yoga-7-2-in-1-14-2k-touchscreen-laptop-amd-ryzen-5-8640hs-with-8gb-memory-512gb-ssd-artic-grey/6571486.p?skuId=6571486). Hope this helps! Feel free to ask more questions in the Q&A section of whatever item you're interested in.
