I have a HR44-500, HR21 and a C41W. The HR21 is used almost exclusively with a original Slingbox so my wife can watch her soap operas on her MacbookPro. I also watch it on the road and it feeds a seldom used 61" projection TV. I have been wanting to upgrade but don't want to spend the money for a new Slingbox 300 or 500. I hate having to change the format to SD and back on the HR21 when we use the Slingbox. I tried a Vulkano box last year and was not happy with picture quality and quirkiness. Thinking of getting a GenieGO and ditching the HR22. I would put the 61" on OTA/DVD only duty. I understand you can stream live (almost) if you first start a recording. Thoughts from those who use the Genie GO? Is it true you can only watch on wi-fi and not 4G or LTE on an I phone? I saw a thread that said a new model/version was due out soon. Any changes?
