Your flash memory will likely outlive the useful life of the touchpad. You'll be worrying about a new battery before you will worry about hitting the file write limit.
Besides that, the march of technology will continue and leave the touchpad well behind. Just the other day I "gifted" a laptop from circa 2006 to an impoverished 8th grade student in need. My almost 2000$ pride and joy gaming laptop, a beast with a massive screen (high resolution, for its day) and a half ton of heft to go with it, putting enough heat off during use to fry eggs. Today? A relic. Its running windows 7 effectively and its still capable as a workhorse thanks to it's still reasonably formidable specs, but its a dinosaur.
My point is, your touchpad will likely fall out of use long before it is physically incapable of running. Five or six years from now you'll be using the latest and greatest without so much as a thought toward the touchpad sitting idle in a drawer or box (or given to your 3 year old as a toy). The flash drive will still be working but you won't particularly care. I've got a box full of these sorts of devices, game changers in their day but destined to rot. Last time I was digging into my "box of forgotten wonders" I pulled out my palm/Sony clie. It was sitting in there on its charging dock waiting on me to pick it back up. Once upon a time it spent every single day in my pocket getting heavy use. I hit the power button for giggles and the green backlit screen fired right up. A few taps of the stylus later and I was reading an ebook I'd placed there in 2002 or 2003 and never finished reading. I turned it back off, set it back on its dock, and gently returned it to the box. Ever reliable as always, and completely useless to me today. Inevitably, the touchpad will join it someday taking up a space somewhere between the laserdisc player and a fully upgraded ibm pc Jr. I might even pick that CLIE back up again, and I'll bet dollars to doughnuts it'll still fire right up.
