What work, vagabond? Just data processing, or does it involve video/audio editing? Presentations??
And how much away from the desk use will it get? Long periods away from power? Networking needed? Wireless necessary??
Depends on all that plus more as to what to get. So, more info, please, then I'm sure some suggestions will come.
Cheers
Mick
BTW, this could probably be in a tech froum, not community.
