Look and feelIt certainly feels lighter and slimmer. Although it is a bit longer than 7290, it has no bulge — it is a plain candy-bar slab. Gone is the scroll wheel on a side, cause of many thumb injuries of real crackberry addicts. Its replacement is a small trackball that on one hand helps to navigate cursor in any direction (no need to hold Alt anymore to move horizontally), but also leads to constant smudges of the screen. The latter is a clear improvement over 7290 -- has great colors and better resolution.
ApplicationsIt generally provides the same assortment of apps, some slightly more upgraded, some identical to the 7290 times. 8800 includes a GPS and BlackBerry Maps is also there. It's fun to use it every once in a while, although inside the city it has trouble locking onto satellites, unless you're standing on a square or in a park. It also has a few media-centric apps (like audio player, video player, improved picture browser).
WorkingKeyboard has been changed from the 8700 series (where it became smaller, yet the keys were all flat, resulting in much harder typing experience) — keys are not flat, they have a slightly curved ridge, serving as support for the fingers while typing. Trackball is very nice and does help to navigate texts much better. One great addition is ability to type (not only read) multilingual text. While the way switching is done could certainly be improved, as well as ability to restrict the number of choices in the "Change Language" dialogue, the feature in itself is really great.
- The way that names and addresses are looked up has been improved a great deal — that happens straight from a to/cc/bcc field (less clicking and scrolling around). In most other respects there is little change.
- Views certainly look better with a higher resolution and true color display. It would have been nice to be able to reduce the size of a header font a little. In fact, this same problem manifests itself in a number of other places.
- Web browser
- Nice toy, with somewhat questionable value, see above reception issues. Also, at least in case of Russia/Moscow street names seem to have been taken from the maps at least 15-20 years old. Which, naturally, leads me to conclude that correctness of a map may well be in the same range... And (again, font problem/higher resolution problem) — dashboard could really use 30% less vertical space.
