I have been a fan of tablet computers since first buying a refurbished TC1100 for $1,600 in 2004. These computers are convenient for business travel. I use them as a writing note pad, telephone, television, DVD player and conference bridge (with the appropriate software such as OneNote, SIP Softphone, Sling Player, VLC and Asterisk).
My newest tablet is a Samsung XE700T1C. It is lighter weight, more powerful, more capable and less expensive than my original TC1100.
