Some highlights:
The first impression of the phone is that it is a bit bulky (thick), although it’s width and height are completely normal.
Unfortunately though, there is no option to set the actual default backlight strength so when the screen is ON, it’s always full-powered.
The S40 devices have a "premium" music application that supports playlists and sorting via various ways (found in the 7390 and 5300/5200 models), but the 6288 comes with the basic music player. All songs are sorted by filename and they are played one after another. You can do previous/next and fast forward and change the equalizer to 6-7 presets, but that’s about it.
The video player is a very basic one and does not support fast-forwarding.
The 2MP camera in the 6288 is very so-so compared to, let’s say, the Sony Ericsson’s also 2MP cameraphone W810i.
Of course, the phone has a few areas where it could have been better. It comes with only 4.5 MBs of free space and the fact that you can use a miniSD does not help you if you want to download or receive via Bluetooth a file that’s bigger or around that size (e.g. an mp3 file). The transfer will just stop, as the phone doesn’t let you specify if you want to save in the card or in the internal memory. Other areas where the phone could be better is in its default theme which I found repulsive in terms of usability, the Active Standby screen where the font is almost unreadable, the "Gallery" where the file manager actions require too many clicks and recognized filetypes arriving via IrDA/BT are not saved automatically in the right folder, the web browser window which does not make usage of the available screen space (there is an unused bar at the bottom of each web page) and the fact that creating IM/GPRS/PTT/email/etc accounts is not as straight forward as it should be (are global "configurations" and you can have different sets of them).

Ah Eugenia is a hard woman to please. She does give this thing a lot of praise, but I chose to highlight the defects she has pointed out.
