i still haven't upgraded my 4150. i've actually recently thought about getting a dell axim x51v as it'd have the new OS, graphics, new CPU, VGA, etc., but i guess i can hold off. i mean really, why should i upgrade? i can switch LCD orientation, overclock to over 500MHz, play games, watch movies, etc., everything that the dell can do. so, i've decided to just not buy one until my baby dies
it's three years old, i bought it right when it came out for $450 and it's still running great. never had to send it in/contact hp, never had to do a hard reset except when I wanted to. the screen is the same as when i bought it. wifi/bt work fine. i mean, hell, this thing is still running all the games i throw at it and play it at high settings!
so, how is your 4150 running ?
i still think it was gay that we didn't get the OS upgrade to WM2003SE

but hey look, there's another OS out there!
