that's very true! probably gonna get a fourth (newer) one soon because all of these are 15+ years old
Which one do you recommend for an MX runner?
Need cheap off craigslist, long battery life, wifi tethering that works, not too huge.
well if 4 hours is good enough then I guess a T410 will probably be fine. if you're buying local than $30 seems about reasonable. it's 14" and a bit heavy but not egregiously so. I don't know about the T420, I don't own one.
