I have tried to wrap my old and feeble brain around "sketching" in the field and all the answers i get are either fairly expensive or there seem to be glitches. I don't really understand "apps" and how they function but I keep thinking that Blackberry is coming out with the new Playbook circa ~March?. Apparently it runs on some sort of tablet OS. So I wonder if / when /what and why would the appraiser want to go with this type device and how would that work? Would it run Apex? and what other uses could you have with the Playbook? Input in the field? Search comps on the MLS from the field? Substitute as a GPS? I mean, really, does this save time enough to justify the expense?...and I am thinking from the perspective of a non-urban, non-secondary market viewpoint. My comps are freqently distant, difficult to locate sometimes. My biggest concern is that the technology is so rapidly changing, one hardly has the wrapper off the package before it is obsolete and you have to relearn the whole thing. I went to ATT and looked at a smart phone, Samsung... Looks great, does great things... costs an arm and leg and then what have I got? An expensive phone with a $100 a month pricetag to boot? I kept my old dumb phone....which I can't do 1% of its capabilities. Am I just too much of a Luddite?
