I have tested EMLID Reach RS lately using MicroSurvey FieldGenius and am happy with how well the receiver performs. Results are good when using a RTK correction link, I was finding centimeter horizontal accuracy is possible in good conditions.
The equipment I was using for testing included a few different Windows tablet, and a Handheld Nautiz X8 with Windows Mobile 6.5 OS.
I have created some quick guides to get going with FieldGenius which can be downloaded from http://helpdesk.microsurvey.com/index.php?/Knowledgebase/Article/View/1436
