I found opera on my old sl-5500 seems to be faster than that on c3k. I am using opera 7.3 on sharp 3.13 rom with sl-5500,with opera 7.55 on cacko 1.23b1/sharp 1.00 rom with c3k. The scroll seems to be more fluent on sl-5500, so does the switch. What made it so strange? computation? hard disk?software?
