Ashampoo will no doubt provide something better in the fullness of time. I`ve found their products to be good and would willingly recommend them to anybody. Like you,I often wonder if it`s worth upgrading.
The answer to that is: If you`re happy with what you`ve got....No.
Then the price comes into the argument...truly, if you like the price, and by the way, the spec of the upgrade then go for it. I haven`t had the offer yet.
