There are 2 models of the HP TouchSmart PC today: the IQ504t and IQ506t. The biggest difference between the two models is that the IQ506t is the model that ships with the TV Tuner built in.
The design of the 2nd generation HP TouchSmart PC is quite a bit different than the 1st generation. The main PC is a much sleeker design. HP describes the design as a "sleek piano black design with elegant espresso side-panel highlights". The unit also comes with a HP Ambient Light that allows users to see their keyboard in the dark. The keyboard is also conveniently able to be tucked under the unit when needed as well which is nice especially if you would like more room.
While the design of this all-in-one PC is impressive, equally impressive is the HP TouchSmart Suite that ships with it. The TouchSmart Suite consists of the following applications:
- HP TouchSmart Music
- HP TouchSmart Video
- HP TouchSmart Photo
- HP TouchSmart RSS Feeds
- HP TouchSmart Browser
- HP TouchSmart Calendar
- HP TouchSmart Notes
These applications take full advantage of the touch capabilities of the HP TouchSmart PC. Navigate through your RSS feeds with the touch of a finger. Go through your calendars by simply touching the screen. Play music, view photos, watch videos - all by touching the screen. In using these applications you can see that HP has invested a great deal in touch capabilities for this PC - which is very exciting. In my own experience trying these applications out myself - I found everything responds elegantly to the move of my finger on the screen. No lag, not hiccups what so ever. It was certainly a "wow" moment for me. If this PC was sitting in your kitchen or living room, to use it all you would need to do is walk up to it and touch the screen - no keyboard necessary.
Side-note: I'd like to note because this PC ships with Windows Vista Home Premium x64 - the TouchSmart Suite of applications work fully under 64-bit.
HP has invested quite a bit in touch technology for the PC. The HP TouchSmart PC is a culmination of 25 years of HP touch technology design and development. HP first brought a PC with touch technology to the market in 1983 with the introduction of the HP 150 PC.
