For a 600 Mhz machine, the GUI is not quite as responsive as I would hope.
The mail client is really, really sucky which makes Nokia look bad... I mean, it's not rocket science to polish something like what they have now into something better.
Makes me think Nokia doesn't care that much, which saddens me...
Still, for me I have some pending things I would like fixed: - better UI on the mail client - more than 4 desktops (... please?) - have app icons show when I install them, not on reboots - better MSN connectivity - intelligent contact merging - better GPS app from Nokia - more responsiveness when I click on IM notifications - assign ringtones to contacts - more than 2 profiles
And a few more "paper cuts" here and there. Overall, it's a great computer with some nice phone features
