DUDE you remind me of myself back when i got the n900, i had a nokia e75, and really i wanted to change, i wanted something other than symbian, something extraordenary, something out of this world, i tested back than tons of devices including the n97, 5800, iphone 3gs, nokia e72, and a lot more, but i didn't test the n900 .
remember this i was a 100 % noob, i never used linux before (i still never used it ) , i didn't even know what x-terminal is, but damm i love my n900, i'm learning skills with it, i know how to reflash, overclock, copy/paste/cut files via x-terminal, i know how to tweak transitions and mods on the device, i know how to do pretty much every simple task with x-terminal, i'm really good with the qb bicon widget...... but i just love all what the device has to offer, and for apps, well i used to have on my old symbians arround 40 downloaded apps, and 20 games, and most of the apps were bookmarks,..... but on the n900 i have 120 apps and games, yes i have 2 times the number of apps that my brother have on his jailbroken ipod touch (yes i jailbroked it ), people say there is no apps, but atually we have tons of them, and 90% of our apps are 100% excellent, ("symbian had like 35% of good apps, rest was (is) crap), the homescreens are just ....WOW, no device can be customized like the n900, you are gonna love it trust me, same way i'm loving mine.
