I'm an 28-year-old art student; my parents set me a pretty tight budget each month for me to manage myself. Our family doesn't have a lot of disposable income so I can't go over $500 (and that's a hard limit). In the past I have used

Basically I just wanna draw and animate on Clip Studio Paint, with a device that is snappy enough that it won't lag.

I have bough two 2-in-1s from Alldocube over the past 2 years, and while the price was nice they both went into various etates of disrepair (my current one is doing well enough except for the fact that its battery went straight down over from 4 hours to 30 seconds after less than a week)

No plans for any intensive gaming.

A battery life of 4 or 5 hours is fine for me, but I'd hope it won't degrade too much too quickly.
