When I picked up the TT1 the unit was pretty quick to respond, boot ups and screen selections etc, but after loading a bunch of apps on it is noticeably slower. There is still about the same amount of free space on the internal memory since I removed some files that come with the unit like European sat images, extra voices etc. But I did notice on one menu I got to it listed the memory at a much lower figure than the TT Home software says. I think according to TT Home I have ~35-40MB free but this indicated <2MB. Is there something I can do to free up this memeory?
