when a friend of mine introduced me to the N900 back in late 2011, i was amazed and said to myself that _this_ is what a smartphone should be like.
coming from an android phone that used an ARMv6 procie (Samsung i5510), the N900 runs circles around it! i mean, real multitasking and a hardware keyboard! though the i5510 had fairly limited hardware to begin with...

funny though that it was android that taught me how not to be afraid of the shell and use linux.
i do have some mising apps that i use daily with android that aren't available on maemo (Pleco, for example). i don't play games anyway so having no games is not a big loss for me; playing with aircrack and wireshark (and messing with my friend's wifi and school's WEP-encrypted network) is already fun enough.

but if there's there's one thing that i truly find lacking in android (okay, maybe not really platform specific, but you get the idea) is the lack of phones with physical keyboards being produced. i know that there are a lot of keyboards with autocorrect and predictive text, it just doesn't feel right and when you speak a language that it isn't well-supported, well...
also, i'm not really a fan of on-screen keyboards. there's no tactility and vibrations do not count. with a physical keyboard, i can text while walking around without looking at the phone!

sorry about the long post/rant.
