My first generation IPP 12.9 has been well cared for & kept in the Apple silicon case & cover. With the quality of Apple hardware, the superb RAM management, & finely tuned software the general use of this IPP will extend past 3 years. I pre-ordered the Vaja case & cover for the IPP 10.5 and intend the IPP 10.5 purchase to be at least a 2 year + investment. Having just general use needs of computer type devices I'm rarely in need of a laptop or desktop (less than once a month). I'll bring my IPP 12.9 for specific reasons and trips, otherwise it'll be kept at the house. The IPP 10.5 will go where I go daily.
