I of course still LOVE my PSR2000, but I'm now seriously considering adding the Tyros to my setup. Here is my list of reasons (from a PSR2000 owner's perspective) to upgrade to Tyros:

1) Intro (3 ea) & Ending (3 ea) variations are now directly accessiable
via buttons instead of having to go into a sub menu.

2) COLOR 'moveable tilt' screen LCD easier to view than fixed
monochrome flat screen

3) Tyros: more foot control pedal configration options: Supports
multi pedal foot controlers. It even includes a dedicated screen
page for configuring the Yamaha MFC10 Midi Foot Pedal Controler
directly from the Tyros. The PSR2000 only supports limited functions
of the MFC10.

4) Keyboard action much better than flimsy kb feel of the PSR2000

5) The new Mega Voices (Strings: Bass, Guitar, violin, etc) sound
INCREDIBLE ! All the other sounds have been re-mastered as well.

6) Styles, though similar & many the same as on the PSR2000, have
been re-recorded at a higher midi resolution providing more punch &
realism, and sounds utilizing string instruments have been replaced
with the new mega voice samples.

7) Mic input volume knob has been moved from the back of the
keyboard to next to the Master Volume knob (a much more convenient
location to afford easy on the fly access).

8) Onboard USER Memory is now 3 MB rather instead of 1 MB on the
PSR2000. Still Would have preferred more, but . . .

9) Tyros supports an optional 'off the shelf' hard drive which
solves the limitation of #8

10) Tyros is relatively lightweight: 27 lbs

11) Real time Dynamic control of accomp parts volume. PSR2000
doesn't have this.

12) USB port to transmit data directly to/from your PC: no more
floppy disk transfers

13) Ability to access & edit Tyros control panel & instrument voices
& efx from your PC computer via Tyros PC software. COOL !

14) Yamaha 'Open Plug Technology' support allows Tyros sound editing
to be performed via 3rd party software like: Cakewalk Sonar &
Cubase.

15) The Tyros loads & plays PSR2000 format Styles w/OTS, as well as
well as loads PSR2000 Music Finder files (abeit minor tweaking)

16) Tyros board looks sleek: the rounded look is out and the angler
look is back.

Downsides to upgrading:

1) Tyros doesn't have on board speakers !
2) Though Tyros is only 3 lbs heavier, it is considerably larger in
size: length, depth, height, so not nearly as portable as the PSR2000
3) Two to three + times more expensive $ than the PSR2000 costs.

Anyone have anything to add, both pro/con?
