The questions is; Which ones?
a) MiniOpera or Chrome Beta?
Take your choice, there are many free browsers, and if you don't like one just delete it.
d) Beautiful Widgets? Still not as good as HTC Sense.
Yup! But lots of launchers have widgets. I haven't tried them all, but...
h) Don't know any Memo app outside Color Notes.
Jotter is getting good reviews, but it's not free so I'm waiting for the ICS upgrade with the premium package. Same goes for browsers and launchers.
i) Sony doesn't make their Reader app available for Europe.
I'm not sure about that one, but there are lots of readers for EPUBs out there. Aldiko is one that comes to mind.
