Panasonic’s modular Toughbook 55 lasts up to 20 hours on a charge venturebeat.com

But today the Kadoma, Japan-based company really shook things up with a new flagship — the Toughbook 55, successor to the Toughbook 54 — that’s almost entirely modular.
That’s standard stuff as far as laptops are concerned, but the Toughbook 55 has a few tricks up its sleeve.
The Toughbook 55 also has the distinction of being the first in its line with a modular design, as alluded to earlier.
And for folks with Toughbook 54 vehicle and desktop docks, they won’t have to toss their equipment — Panasonic says the Toughbook 55 is backward-compatible with nearly all Toughbook 54 accessories.
AvailabilityThe Toughbook 55, which comes with a three-year manufacturer’s hardware warranty covering materials and workmanship, is available starting today from $2099 through authorized Panasonic resellers.
