Lawyers need to be concerned about security and confidentiality. Much of what we carry with us is not very secure. Many lawyers carry USB drives, smart phones, tablets, and laptops that are neither encrypted nor password/pin protected. This is disaster waiting to happen. So why not carry a more secure, but very useful laptop-type device that costs less than a month's worth of lattes?
I've written several times about the utility of cheap Chromebooks for lawyers. Now one of the better Chromebooks (if you don't mind refurbished) is even cheaper at $110 directly from Acer's Ebay store. This is the rather stylish white C720 model with an Intel Celeron processor that is quite zippy running Chrome OS.
Once you have your Chromebook, which requires you to create a free Gmail account to use effectively, remember to maximize the security of an already secure machine by enabling second factor authentication on your Gmail account.
