You can tell the Sam users how underpowered it is all you like, but it doesn't change the fact that it's not.
I beg to disagree, it IS underpowered for quite a lot of tasks (just like most other PPC-hardware), especially considering the price. Amiga-users are just too used to tweaking their own habits around what the machine is (in)capable of doing, but it's 2012 and a "new" machine should be able to perform tasks that PC's have been doing for the past 10 years.
But that doesn't change the fact that using the machine can be fun, because it is fun. But trying to convince yourself that the machine isn't underpowered (compared to anything else on the market today) and somehow arguing that the price isn't crazy high is just silly. Hobbies are expensive and they don't need to be sane
