really amazing keyboard -- the typing be just perfect , and so be the way it fold . battery life be also simple and great . this keyboard make it possible to write papers and proposal on my pocket pc while I travel . since my laptop die , I decide to just use my pocket pc for this purpose instead . I buy this keyboard and a mouse , take it on the road for a week and it work fine . it be great to travel so light -lrb- you really do feel a lot lighter compare to even a ibook -rrb- . ergonomically it be quite comfortable for I to type on this keyboard and use a mouse while look at the Pocket PC screen on the stand . the only downside in that respect be that you can not see too much text at once on screen , so I feel the need to make printout of my document -lrb- at hotel business center etc. -rrb- a little more often than I normally would with a laptop , to review the draft I be work on `` as a whole '' . there be a few caveat to be aware of if you be contemplate a pda with this keyboard as a replacement for a laptop , because the result setup be miss a few thing that one take for grant with a laptop : - I need the mouse too . it be too hard to stop typing on the keyboard and pick up the stylus , and although there be keyboard shortcut for many thing , at least in a week I could not get the hang of they . stowaway 's Bluetooth mouse work perfectly for this , and be a great product also . because the whole setup be so compact , I could even use it with the mouse on a airplane tray table in coach , where normally a mouse will not fit next to a laptop ; on the plane this setup feel - more - comfortable than a laptop to I . - because the built-in stand be necessary -lrb- you can not very well hold the pda while you type , plus the IR transmitter be attach to the stand -rrb- , you can only put you pda in certain position : -- in portrait orientation , the position of the PDA 's power connector at the bottom of the pda prevent you from charge the pda while you type -- which can be a problem since , although keyboard battery life be great , the PDA run out of juice after a couple hour if you be use it like you would use a laptop -lrb- typing , mousing , listen to music at the same time , etc -rrb- . plus , if you have a extended battery pack for you pda , the extra protrusion in back prevent the pda from seat securely in the stand , although it could kind of rest on it if I be not in a bumpy environment like a train or plane . as a result , for I when my standard battery pack would run out , thing would get a little sketchy . -- Landscape orientation be possible , but only in one direction not the other -lrb- due to the location of the Stowaway 's IR transmitter -rrb- . on my pda that orientation on the stand prevent I from use headphone -lrb- because the jack wind up on the bottom -rrb- . I could charge the pda while it be in this position , but the protrusion of the charge connector to the right again make the PDA rest insecurely on the stand , at a weird angle . - this detail do not really bother I but figure I would mention it . this keyboard , I think unlike the Bluetooth version from the same manufacturer , need to be use on a rigid tabletop -lrb- not you lap -rrb- . otherwise , the keyboard fold back into a `` v '' under the weight of you hand . basically , it be perfectly solid in a hotel , on a airplane , on a Amtrak , but do not expect to use this setup on a commuter train with no tray table ! but I can not really imagine how you would arrange the PDA to look at it comfortably without a tabletop anyway . so , while everything work great technically and even ergonomically , beware of unexpected physical constraint . after I get back from my first trip , I decide to return this keyboard and order the Bluetooth version , which communicate with the PDA via radio rather than invisible light , and which be also compatible with my pda . I be wait for it to arrive . since the mouse be Bluetooth , I figure it make sense to get the Bluetooth version of the keyboard as well . maybe it will lengthen battery life on my pda a little since Bluetooth need to be activate to use the mouse anyway , and now I can turn off the PDA 's infrared sensor . and I be hope that the stand for the Bluetooth version will be more flexible since there be no need for a line-of-sight IR transmitter . FYI , my pda be a Dell Axim x30 with Bluetooth .
