That is indeed very interesting and a significant difference in design. I would say without doubt Humax appear to have added further cost cutting measures to a product that was already cut to the bone.
I suppose in their defence Humax will argue they have to make them to 'a price' in order to make a profit. Well that's all well and good but the product should meet certain standards and one wonders what those standards now are.
Pity you can't see one of the Humax BT Youview models in operation Minstrel as I am really pleased with the performance of mine - much better than my 2000T.
