Thanks for the responses. The reason I am going with the XEGS is because one has been offered to me new in box for a very reasonable price by someone who had it sitting in storage. So for me, it is being considered a starting point, I may take Goochman's advice on alternate computers at a later date when I am further into the Atari ecosystem.
The main reason that I'm looking for a solution similar to the Harmony Cart but for the XEGS is because others in my family who love to play classic games are not quite so technically inclined, like enough so that they can use the Harmony or other similar devices without any problem, but a Windows computer running MAME confuses them if it doesn’t work exactly as expected, so I’m trying to simplify it as much as possible. When I look at the videos for the AtariMax MyIDE, it looks like something I could set up initially, give them some instruction as it does seem more complex, and then take it out as needed when I want to explore additional peripherals and software, such as the floppy drive, etc… Does this sound like a fair assertion?
Along that same line, I am actually looking to get a Floppy Drive for it eventually (I have serious nostalgia for the 5¼ disks), is the 1050 my only choice with an XEGS?
