What iPad and laptop is best to use working from home working remotely with telehealth platforms

An iPad and laptop computer typically fill different usage needs. Both have strengths - and together can be powerhouse of flexibility. For maximum integration, an iPad and an Apple Mac (in preference to a Windows PC) might be good choice. As for your usage in Telehealth, perhaps seeking advice from other colleagues in your industry would be your best option.

All iPad models have broadly the same core capabilities. Models essentially differ in their ultimate performance and physical attributes. iPad Pro models use FaceID for biometric user-authentication, while others use TouchID.

The basic iPad is the entry-level iPad - robust, flexible, but lacking the high performance and capabilities found in more advanced models. These are often used in Educational settings and retail. The iPads Pro are the opposite end of the scale - top of the range, with cutting edge capabilities and hardware with either an 11" or 13" OLED screen. Between these two extremes are the iPad Air models, offering a mid-range high performance option with 11" or 13" LCD screens. The iPad mini (A17 Pro) is perhaps an entirely different proposition - offering a smaller form factor and other differences in hardware and ultimate capability.

All current models of iPad support Apple Pencil - although you must take care to ensure that you select the correct Pencil from the four different available versions. If you intend to use an Apple Pencil with iPad, ensure that you choose the correct Apple Pencil for your chosen iPad - as they are not interchangeable. Here is the definitive compatibility list:

Whichever iPad model you choose, you would be well advised to purchase as much internal storage as your budget might reasonably allow - as internal storage (and other hardware) cannot be changed, upgraded or extended. The available internal storage is fixed for the entire life of the device. If you run out of internal storage for your documents, photos and other data, you will forever struggle and become a source of frustration. It is far better to have more storage than you need, than to need more storage than you have.

A good rule of thumb is to quantify how much data storage you will need - add a healthy margin - then double it. If you are unable to quantify your data storage needs, it becomes more difficult. Whilst I and others cannot make definitive recommendations for your personal needs, objectively I would council against purchase of any iPad with any less than 256GB storage, 512GB and higher having a greater margin for growth.

Within the Apple Support Communities we see regular tales of woe and disappointment when storage requirements are exceeded, necessitating replacement of the device; by contrast, we never see complaint of having too much available storage. It is relatively easy to fill limited internal storage space; perhaps consider higher tiers of storage as providing room for growth as your needs develop or mature - potentially extending the useful usable life of the device. 

Also consider the functional differences between WiFi Only and WiFi+Cellular models of iPad. Aside from the obvious Cellular functionality, only WiFi+Cellular models include GNSS/GPS location capabilities - which may impact any Apps or features that require accurate and consistent location data, such as Mapping. 

Purchase of a WiFi+Cellular model provides access to precise location services, but does not commit you to using Cellular connections. WiFi Only models of iPad have no Cellular or GNSS/GPS functions at all.
