It depends on what features you want to have on your phone bai. Barely a month ago, I had to choose between the N73 & K800i.. I chose the N73 because I want the flexibility of the Symbian OS, not contented with Java lang. Hehe. For a smartphone, I would say its better and faster than the previous symbian phones, being S60 3rd Ed.. Problema lang ani nga phone (as with recent N-series phones, e.g. N80, N91, N93), kay ni decrease na ang RAM (reportedly 20MB) as compared to the ever-versatile N70 (32MB). Mas limited na nuon ang multitasking experience.. pero what's the use of opening up numerous applications all at once, di ba? Hehe. Tagsa2x lang gud pag open.

Nah, don't really care, basta contented ra ko sa N73. Hehe.
Pero if you were to compare it to the K800i, which is not symbian based, mas pas2x jud ug response time ang K800i. My gf has a K800i, had the chance to compare feature by feature, mas pas2x jud. Pero dali ra ko mapul-an ato. Hehehe. Want to play a lot with my phone man sad. If you're in for the camera feature, go for the K800i. Lahi ra jud ang gawas. N73 is good for outdoor pics and on areas with good lighting conditions. Sa dark areas and at night, naa jud ning "Nokia Blur"..

Sa sound quality sad (at speakerphone mode), mas ni prefer ko sa K800i even though 1 speaker lang to. Mas loud ang N73 with 2 speakers pero inferior jud sa sound quality when paired with the K800i..
But overall, I prefer the N73. Good picture quality. Good battery life, despite the bigger screen. Very versatile phone. S60 3rd Apps are growing in number steadily man sad. Even though walay wifi, ok ra. Don't need wifi. Hehe.
