Cell Phone, Tablet, Laptop, Computer... Only too old if it's not doing what you need it to do.
The only reason I upgraded my six year old cell phone (that did take a swim in the kitchen sink a few years ago), was because they offered me a free upgrade. Otherwise, I'd still be using it (I could still make my phone calls and text the people I needed to).
If my last laptop hadn't completely died, I'd probably still be using that as well. Same with my current tablet. Still working (albeit quite slowly) but still sufficient for my needs.
