dont worry dude! i got n900, first one had reboot problem but i just replaced it today from the nokia store and this one is working perfectly so far no reboots, mic working, no dead pixels. or anything. great! n im new to linux never never used linux. total noob here. iphone was my first touchscreen phone used it for a month then sold i felt really limited using it. but now hell yeah even right now im using my n900 and doing voice chat at the same time lol. im totally amazed what this device can do. anyway just keep your fingers crossed and wish you get a stable unit. other than im totally happy. =D i had no high expectations so im definitely satisfied with it.
