It is so funny watching text fly into my T-Mobile SDA smartphone (aka iMate SP5m or HTC Tornado) using the Stowaway keyboard. This keyboard is all class: just like a laptop keyboard, with the same spring to the keys, quality, durability and lovely looks to boot.Entering numbers is get-used-to'able, however symbols such as () and & or % can be a major pain, due to the fact that a) you have to use "custom" key commands using ctrl, fn1 and fn2 buttons and b) if you are an experienced typer, you "already know" the "motion" for & or * or (), and you'll find yourself doing them! (meaning you are incorrect, on this keyboard)That said, entry is obviously very fast and natural as this is a proper keyboard, just with some multi-purposed keys requiring key combos.The only solution is to FORCE yourself through it and just do it. You will get used to it, just like you got used to fast touch-typing.Anyhow, this thing is a gem for hammering out quick SMS text messages, etc. I mean no more "click-click-click, clack-clack, click-click-click-click, clack-clack" to type out a single four-letter word. Nothing feels quite like that lol!This thing will fit EASILY in a purse and will fit in a men's pant pocket. I wear shorts, pants, etc. and it fits fine.The keyboard clicks are quite silent. I use this in class to quicly type out extensive class notes, as I can type far faster (and more legibly) than I can hand-write.The case is durable sandblasted aluminum (like my old minidisc player) and the detachable device stand is sweet! I use it all the time to put my phone on one of those little chair-mounted desks in class, and type in my lap. Sweet!Anyhow, is this thing essential? I mean, I kinda hate not having a notebook around when in, say, a statistics class with graphs and stuff...you can't draw graphs with this thing very well. However, for text-based notes in a college setting, this thing is well worth it. A smartphone as above and a keyboard, and you have one of THE major functions of a laptop, but without having to carry a laptop. Just the phone you'd have anyways, and this flat little thing.NOTE: if you have troubles reconnecting this thing, use the bluetooth connect on your phone first, then use the special driver provided by Think Outside to finish the connection. Two part process.In all, I am a college student and I wish I did not have to pay over $80 for this unit (why can't they make it for $30?), but in the end this thing is slightly sweeter than it's price, so it's worth it.
