Hey, Cg101. Any pen that uses MPP or AES pen protocols will work with this Yoga 7i 2-in-1. For example, this Lenovo Digital Pen 2 (https://www.bestbuy.com/site/lenovo-digital-pen-2-gray/6580719.p?skuId=6580719) supports AES pen protocol and works well with Yoga pen enabled devices.

Hey, Mike. Regarding the subscription, in short, no. Microsoft Office is built-in to the Windows 11 operating system with the apps preinstalled; however, without purchasing a long-term Office solution, such as Microsoft 365, only a 30-day trial can be activated out of the box. Here is a link to the Microsoft Office landing page on bestbuy.com to learn more about your Office options (https://www.bestbuy.com/site/microsoft/microsoft-office/pcmcat748300511466.c?id=pcmcat748300511466). Given how you plan on using this Flex 5i, if the size of the device and its features and specs meet your needs, it seems like it could be a good fit for you. If it would make you more confident, for guidance in finding the right computing solution, we recommend going into Best Buy stores and working with an advisor to get expert help or you can virtually shop with an expert online via this Best Buy online link: https://www.bestbuy.com/services/triage/shopping?cat=cnt&subcat=comp

Hey there, thank you for your question. Yes, the open-box items are eligible for the full 1-year limited manufacturer's warranty applicable for current Lenovo Yoga 7 devices. If the unit you purchase has a warranty duration that does not reflect this, we recommend reaching out to Lenovo Support, as once given a proof of purchase, they should be able to reinstate your manufacturer warranty to its original duration.
